File folder with individual holding units

Abstract

A file folder includes a rail member fixed to the connection portion of the file folder and the rail member includes a plurality of ribs extending from a surface thereof so as to define grooves between the ribs. The grooves communicate with openings in a top end and a lower end of the rail member. Each rib has a head on a distal end thereof and the head is wider than a width of the rib so as to form a narrow entrance corresponding to each groove. A holding unit has an elongate insertion which includes an enlarged ridge on a side thereof so as to be slidably inserted into the grooves via the openings and the insertion is sized to be slidably engaged with the narrow entrance. Document is positioned or collected by the holding unit.

Description

FIELD OF THE INVENTION

The present invention relates to a file folder with individual holding units which are slidably connected to the file folder and can be removed from the folder individually.

BACKGROUND OF THE INVENTION

A conventional file folder generally includes a front cover, a back cover and a connection portion which connects the front cover and the back cover side by side. Document is received between the front and back covers. However, the document easily slips out from the file folder so that some manufacturers install plastic pockets to the file folder and the document can be received in the pockets. When using the document, the user has to pull the document from the pockets and the sheets of the document are not well positioned and easily blown away. After the document is used, the sheets have to be organized and put into the pocket and this may require a lot of time.

The present invention intends to provide a file folder which includes individual file holding units which are able to be removed from the file folder individually and to collect the sheets of document by fasteners.

SUMMARY OF THE INVENTION

The present invention relates to a file folder which comprises a front cover, a back cover and a connection portion which is connected between two ends of the front cover and the back cover. A rail member is fixed to the connection portion and includes a plurality of ribs extending from a surface thereof so as to define grooves between the ribs. The grooves communicate with openings in a top end and a lower end of the rail member. Each rib has a head on a distal end thereof and the head is wider than a width of the rib so as to form a narrow entrance corresponding to each groove. A holding unit has an elongate insertion which includes an enlarged ridge on a side thereof and the enlarged ridge is sized to be entered into the opening and the insertion is sized to be slidably engaged with the narrow entrance.

The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 4, the file folder 1 of the present invention comprises a front cover 11, a back cover 12 and a connection portion 13 which is connected between two ends of the front cover 11 and the back cover 12. A rail member 2 is fixed to the connection portion 13 by rivets and includes a plurality of ribs 22 extending from a surface thereof. Grooves are defined axially in the rail member 2 by the ribs 22 and communicate with openings 23 in a top end and a lower end of the rail member 2. Each rib 22 has at least a head 221 on a distal end thereof and the head 221 is wider than a width of the rib 22 so as to form a narrow entrance 21 corresponding to each groove.

A holding unit includes an elongate insertion 3 and two side plates 32, wherein an enlarged ridge 31 is formed on a side thereof an the two side plates 32 extend from the other side of the insertion 3. The two side plates 32 are flexible and can be pivoted toward each other as shown in FIGS. 3 and 4. The enlarged ridge 31 is sized to be entered into the opening 23 and the insertion 3 is sized to be slidably engaged with the narrow entrance 21. The enlarged ridge 31 of the insertion 3 is then stopped by the heads 221 on the ribs 22 and the holding unit cannot be separated from the rail member 2 via the narrow entrance 21. A plurality of first fasteners 321 and second fasteners 322 are located on the two side plates 32 respectively. In this embodiment, each of the first fasteners 321 is a protrusion and each of the second fasteners 322 is a tubular member in which the protrusion is removably inserted.

Document composed of sheets 4 are located between the two side plates 32 and the first fasteners 321 extend through holes in the sheets 4 and are engaged with the second fasteners 322 to position the sheets 4. The holding unit is connected to the rail member 2 by inserting the enlarged ridge 31 into the groove via the opening 23 in either the top end of the lower end of the rail member 2. The user can remove the holding units individually from the rail member 2.

FIG. 5 shows another embodiment of the file folder wherein the holding unit does not have the side plates 32 as shown in the previous embodiment and a plurality of plastic pockets 33 are connected to the other side of the insertion 3. Sheets 4 can be collected in the plastic pockets 33.

While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the, scope of the present invention.
