Description

Background of the Invention

1. Field of the Invention

The present invention relates to a file device and binders to be used for such file device. More particularly, the present invention pertains to a file device for filing thin sheets of recording medium, such as photographic pictures, slides, medical specimen plates, floppy discs and the like. The present invention further pertains to components to be used in such file device.

2. Description of the Prior Art

The Japanese patent application Sho 63-241935 filed on Sept. 27, 1988 and disclosed for public inspection on Mar. 29, 1990 under the disclosure number Hei-02-089699 discloses a file sheet adapted for filing thin recording sheets such as photographic slides. The file sheet is made of a thin plastic sheet formed with recesses adapted for receiving the slides. A plurality of such file sheets are bound in suitable binding covers with photographic slides fitted to the recesses of the sheets or that the slides are filed in a readily accessible manner.

In binding such file sheets, file covers having binding rings provided at appropriate spacings may be used. The file sheets may then be formed along an edge portion with binding holes with spacings equal to the spacings of the binding rings so that the binding rings are fitted to the binding holes in the file sheets. This type of file sheet binding device is advantageous in that the file sheets can be added as desired. It should however be noted that in order to bind an additional file sheet the rings are at first opened and the file sheet is engaged at the binding holes with the rings thus opened. Thereafter, the rings are closed to hold the file sheet together with previously bound file sheets. Thus, binding an additional file sheet requires a troublesome task.

Another problem encountered in the aforementioned sheet binding device is that turning over the file sheets is not convenient. More specifically, in this type of binding device, the binding rings are generally of a large size so that a large number of file sheets can be accommodated. The binding rings of such large size have a tendency of making turning over the file sheets difficult because the file sheet may have a tendency of sticking to the binding rings by being inclined with respect to the row of the binding rings.

Summary of the Invention

It is therefore an object of the present invention to provide a filing device for file sheets in which binding of the file sheets can readily be made so that additional file sheets can be easily filed.

Another object of the present invention is to provide a file device for file sheets which is simple in structure and convenient to use.

A further object of the present invention is to provide a file device which is convenient to change the binding capacity.

Still further object of the present invention is to provide a file device which is compact in size.

According to the present invention, the above and other objects can be accomplished by a filing binder comprising a plurality of elongated binding members made of a resilient material, each of said binding members having a groove extending along the length of the binding member and formed with a slit opening opened at one side, said groove being of a cross-sectional configuration which is enlarged from said slit opening toward transverse inward direction, said binding members being arranged in side-by-side relationship with said slit openings directed to the same orientation and connected together by flexible connecting means.

According to another aspect of the present invention, there is provided a file sheet having ridge means formed along one edge portion thereof. The file sheet can be filed in filing binder by having the ridge means engaged with the groove of the binding member of the filing binder.

The binding member may be made of a rigid plastic material and the connecting means may be a weld between adjacent two binding members. The binding member may be formed with the groove having slit openings at the opposite sides. The connecting means may then be one or more connecting members having projections arranged in side-by-side relationship, each of said projections being adapted to be engaged with one of the slit openings in each of the adjacent binding members.

According to another aspect of the present invention, the binding member has a pair of opposed pawls forming a slit opening therebetween. A plurality of such binding members being arranged in side-by-side relationship with the slit openings oriented in the same direction.

According to a further aspect of the present invention, there is also provided a binding member including a plurality sets of holding means each comprising a wall and a holding member made of a resilient material, said holding member having pawl means directed toward the wall to hold a file sheet between said wall and said pawl means, the plurality sets of holding means being connected by resilient connecting means.

The binder comprising the binding members which are connected together as described above may be provided with cover sheets so that the file sheets bound in the binder are covered by the cover sheets.

According to a further aspect of the present invention, there are provided a plurality of connecting members each comprising a pair of binding members of the aforementioned structure. The pair of binding members in each connecting member are connected together with the slit openings oriented in the same direction. There are also provided a plurality of file sheets each having ridge means along each one of opposed sides for engagement with the groove of the binding member. The file sheet is bound to one of the connecting member by having the ridge means at one side engaged with the groove in one binding member of said one connecting member. Further, the same file sheet is connected with another connecting member by having the ridge means at the other side engaged with the groove in one binding member in said another connecting member. The other binding member in the first mentioned connecting member is connected to a further file sheet by having the ridge means in the further file sheet at one side engaged with the groove of the said other binding member. The other binding member of the second mentioned connecting member is also connected with a further file sheet in a similar manner. In this manner, a plurality of file sheets are foldably connected by a plurality of connecting members.

According to a further aspect of the present invention, a plurality of binding members are connected together at the sides opposite to the grooves in a manner that a hinge movement is allowed between two adjacent binding members. A spine or shelf back is attached to the outside of the connected sides of the binding members and cover sheets are provided at the opposite sides of the spine in a manner that the cover sheets can be opened outwardly. Each of the cover sheets is provided with means for engagement with the groove of the binding member and the cover sheet is connected with the outermost binding member by having the engagement means engaged with the groove of the outermost binding member.

As described, the present invention provides a binding member which is of an elongated configuration and has a longitudinally extending groove formed with a slit opening opening at one side of the binding member.
