Description

The utility model relates to a folder, in particular to a file folder structure that can quickly clamp files by pushing with fingers.

Please refer to FIG. 1 for a conventional folder, which is mainly composed of a clip body 10 and a jacket 20 . The clip body 10 is integrally formed of plastic materials, and its cross section is U-shaped with a clamping distance 11, and contains an upper clip 12 and a lower clip 14, and a clip is formed on the clamping side edge of the upper clip 12 and the lower clip 14. 18, and a rectangular hollow part 15 and a limiting piece 16 are provided on the middle part of the upper clamping piece 12.

The jacket 20 is composed of front and rear jackets 22, 24 and a clip back 26 formed at the bent end. Please refer to the enlarged view of Fig. 2 again, the clamp back 26 middle part on the rear jacket 24 and relative to the limit piece 16 of the lower clip 14, the forming protrusion is provided with a limit projection 27, and in the limit projection 27 A limiting groove 28 is recessed.

Its combined use is to sandwich the jacket 20 in its U-shaped clamping distance 11 through the clamping mouth 18 of the clamping body 10, and then press down the jacket 20 at the same time with the fingers of both hands to slide the U-shaped bottom surface according to the clamping distance 11 , let the limit bump 27 be positioned under the rectangular hollow part 15, and then release the fingers of both hands, so that the raised limit bump 27 can be limited in the rectangular hollow part 15, and the document 30 (paper) is Clamped between the front jacket 22 and the rear jacket 24 . The composition and structure of folders in the past is not perfect and has the following shortcomings:

First, the document 30 is clamped by the single limiting piece 16 of the clip body 10 and the limiting groove 28 of the jacket 20. When there are very few documents 30 to be clamped, the left and right sides will be generated due to the "single clamping point". The situation of offset slippage, as shown in FIG. 3 , is more obvious when there are fewer clamping files 30 . When there are many documents 30 to be clamped, and the clamp body 10 has only a single clamping point (unbalanced force application point), it is difficult to clamp the documents 30 .

Second, another disadvantage in the use of conventional file folders is that the surface of the formed clip body 10 is slippery. When the finger pushes the clip body 10 to clamp the document 30, it is easy to slip and the touch is not good during the force application process, which makes the fingers sweat easily. moreover, because the thickness of the U-shaped bending portion of the clamp body 10 is insufficient, the number of clamped documents 30 caused by it is not many.

The main purpose of the utility model is to provide a folder that is easy to clamp files, has a large number of clamps, and does not need to worry about slipping.

The file folder of the utility model is characterized in that: the thickness of the U-shaped bending part of the folder body is thicker than that of the upper and lower clips, which can be used to clamp more files than before, and the bottom surface of the lower clip is flush with the two ends. Limiting lugs are provided on each side edge, and the surrounding and bottom surfaces of the limiting lugs are curved, so that the clamp body can be set in the groove of the jacket to balance and slide smoothly back and forth, easy to clamp files and do not worry Slip.

Between the flat surface of the bottom surface of the lower clip and the curved surface of the limit lug, there is a predetermined distance in the molding, and the middle part of the top surface of the upper clip of the clip body forms a semicircular rough shape design that is pressed by the fingerprint of the thumb. , and the relative position of the lower clip is also designed with a strip-shaped groove surface, which provides easy force for the index finger fingerprint and saves pressing effort.

The utility model is described in detail below by preferred embodiment and accompanying drawing, in the accompanying drawing:

Please refer to FIG. 4 , the folder in the preferred embodiment of the present invention is mainly composed of a clip body 50 and a jacket 60 . The clip body 50 is integrally formed of plastic material, and its cross-sectional curved arc is a U-shaped clamping distance, and contains an upper clip 53 and a lower clip 54, and the opening ends of the upper and lower clips clamp side edges to form a clip. Mouth 59, the paper document 70 is clamped in the jacket 60, and clamps the jacket 60 with the clamp mouth 59 of the clamp body 50;

It is characterized in that: the bottom surface of the lower clip 54 of the clip body 50 is flush with the surface 55 and the side edge of the end is respectively provided with a limiting lug 56 , and the limiting lug 56 has a curved surface 57 . Please refer to Figures 5 and 6, and in conjunction with Figure 4, a predetermined distance D is formed between the bottom flat surface 55 of the lower clip 54 and the curved surface 57 of the limiting lug 56, and the distance D is used in this embodiment. In the example, it is 0.3mm, so that the two limit lugs 56 of the clip body 50 can be positioned in the wire groove 62 corresponding to the jacket 60 and can slide forward and backward in balance and smoothly, and can pass through the distance D and the thickness of the jacket 60 Equal, used to accommodate the thickness of the 60 pieces of the jacket, so that when the two position-limiting lugs 56 slide back and forth in the jacket 60, the raised height of the 60 pieces of the jacket does not exceed the lower clip 54 Because during the front and rear sliding of the two limiting lugs 56, they will not be blocked by the corners of the side panels around the jacket 60, wire groove 62, resulting in the situation of lifting the panels, ensuring excellent performance. The sliding effect is achieved with extremely durable sliding path construction features.

Moreover, a semicircular rough shape 52 is designed and formed in the middle of the top surface of the upper clip 53 of the clip body 50 to cooperate with the thumb fingerprint to press and move, and the relative position of the lower clip 54 is also designed to cooperate with the index finger. The groove 58 allows the clip body 50 to be pushed and clamped by clamping the jacket 60 in a labor-saving manner, and the thickness of the U-shaped bending part 51 of the clip body 50 is 2.5mm in this embodiment, which is higher than that of the upper clip 53 and the lower clip 54. 1.5mm thick, through this strengthening structure, the distance between the upper clamping piece 53 and the lower clamping piece 54 can be increased, which can be used for clamping more documents 70, and the second wire slot 62 cut on the jacket 60 can be used every Round holes 64 are provided at both ends of the line slot to ensure that the two limiting lugs 56 slide smoothly in the line slot 62 , and they are blocked by the round holes 64 so that there is no need to worry about the cracking of the line slot 62 .
