FILING APPLIANCES; FILE CARDS; INDEXING (reading desks A47B19/00; book rests A47B23/00) ## Abstract A file, consisting of a cover and at least two securing members, each securing member consisting of an oblong, narrow lacing portion, pointed at one end and connected at its other end to a foot portion which is short and wide with respect to the lacing portion; said cover being connected to a support sheet, wherein at least two inserting openings, which are wide with respect to the foot, and pertaining to each inserting opening, at least one protruding opening and one securing opening are provided; said protruding openings and securing openings being narrower than the foot of the securing member so that the securing member is insertable and lacable with its point through the inserting opening and subsequently through the protruding opening resulting in that the foot will be hooked on the support sheet at the protruding opening, whereas after possibly lacing the lacing portion through sheet material to be filed in the file, the point of the lacing portion is insertable through the securing opening; the distance between the inserting opening and the pertaining protruding opening is larger than the length of the foot portion, measured along the longitudinal axis of a securing member. ## Claims ### Claim 1 A file, comprising a cover and at least two securing members, each securing member being formed of an oblong, narrow lacing portion pointed at one end and connected at its other end to a foot portion which is short and wide with respect to the facing portion; said cover being connected to a support sheet wherein at least two inserting openings, which are wide with respect to the foot, and pertaining to each inserting opening, at least one protruding opening and one securing opening are provided, said protruding openings and said securing openings being narrower than the foot of the securing member so that the securing member is insertable and lacable with its point through the inserting opening and subsequently through the protruding opening, resulting in that the foot will be hooked on the support sheet at the protruding opening whereas, after possibly lacing the lacing portion through sheet material to be filed in the file, the point of the lacing portion is insertable through the securing opening; the distance between the inserting opening and the pertaining protruding opening being larger than the length of the foot portion, measured along the longitudinal axis of a securing member. ### Claim 2 (depends on 1) A file according to claim 1, characterized in that the inserting opening is a straight cut in the support sheet. ### Claim 3 (depends on 1) A file according to claim 1, characterized in that the distance between the inserting opening and the pertaining protruding opening is substantially within the range of two to four times the lenght of the foot portion, measured along the longitudinal axis of a securing member. ### Claim 4 (depends on 2) A file according to claim 2, characterized in that each inserting opening is positioned obliquely relative to the back of the file and that none of the inserting openings are mutually in line. ### Claim 5 (depends on 1, 2, 3, 4) A file according to any of claims 1 to 4 characterized in that two protruding openings and two securing openings pertain to each inserting opening. ### Claim 6 (depends on 1, 2, 3, 4) A file according to any of claims 1 to 4, characterized in that the support sheet is secured to the cover near the back section of the cover. ### Claim 7 (depends on 6) A file according to claim 6, characterized in that the support sheet is secured, by means of staples, to the cover at the back section of the cover. ### Claim 8 (depends on 1, 2, 3, 4) A file according to any of claims 1 to 4, characterized in that the support sheet consists of the inwardly folded extension of the rear face of the cover. ### Claim 9 (depends on 8) A file according to claim 8, characterized in that between the rear face of the file and the support sheet formed by the extension of the rear face, a sheet of cardboard is provided. ### Claim 10 (depends on 1, 2, 3, 4) A file according to any of claims 1 to 4, characterized in that both at the lower edge as well as at the upper edge of the support sheet at least one inserting opening with at least one pertaining set of a protruding opening and a securing opening are present, the distance between the protruding openings of each set of two cooperating protruding openings being equal to the distance between the series of perforations at both edges of a strip, as used in a computer for recording data from the computer. ### Claim 11 (depends on 10) A file according to claim 10, characterized in that moreover at least two inserting openings with each at least one pertaining set of protruding and securing openings are present at locations positioned more to the center portion of the support sheet adjacent the back of the file, the distance between two protruding openings, each belonging to a different inserting opening, being a usual distance for the perforations for a file. ### Claim 12 (depends on 1, 2, 3, 4) A file according to any of claims 1 to 4, characterized by an almost completely cut out section of the support sheet, said section being provided with tongue-forming notches, said tongues being insertable into cuts in the support sheet, said cuts being positioned in such a way that the section, then teared out of the support sheet and mounted by its inserted tongues, protrudes outside an edge of the rear sheet of the file in order to form an identifying tab. ### Claim 13 (depends on 1, 2, 3, 4) A file according to any of claims 1 to 4, characterized in that the securing opening is in the configuration of an arc-shaped cut.
