Toronto / Oanada (Ontario) Stapling device for punched sheet documents

The invention relates to a stapling device for stringing and detachable fastening of perforated sheet documents of all kinds in folders, by means of guided through the perforations of the sheet documents flexible rod-shaped stringing elements in the form of Pearl rods, the pearls of which are connected to one another by spacers of smaller diameter than the pearls.

So-called split ring binders are used for the same purpose, in which the perforated leaves are opened by means of a gap in the ring can be lined up on this and can be conveniently removed individually and reinserted into the stack in the correct order. The main shortcoming of this type of storage is that the Stack of sheets takes on misshapen dimensions in the course of time and is difficult to accommodate several in the work area, the sheets

Very evacuating directions by which the leaves are compressed into a book-shaped shape will. However, such devices are relatively expensive to manufacture and sensitive and cumbersome to use, especially when removing and reinserting sheets. ■

So-called loose-leaf binders, in which the loose, perforated sheets of paper can be lined up on flexible metal strips, are widespread are that are attached to the üückenteile a portfolio and after lining up the sheets with their free ends after attaching a ü End strip bent and on this by sliding elements are lockable. - -

Also formed with them bleiben- _■:; de Bends that are difficult to remove, so that there are often difficulties in removing and re-arranging sheets, especially when the stack of sheets has reached a greater thickness. Furthermore, the sheets tear easily at the sharp edges of the aligning strips.

} For these reasons, loose-leaf binders of this type are suitable for the7 not large stacks of sheets, especially if the sheets are of an above-normal format, even if the one-time parts of the flat file receive a stronger education. .

■ Have letter folders with rigid but separable receptacles j has some advantages over normal flat files, however Even with them, the capacity of leaves is limited because individual leaves can be removed and reinserted in the filled State of the folder makes trouble. The filing mechanism takes up a relatively large amount of space and the space required

of the folder is just as big when it is empty as when it is filled State.

Purpose of iCrfindung is using the basic principle it .reihstreifen on-the quick stapler of alignment of the leaves to "flexible to provide a stapling device that does not have the shortcomings of conventional loose-leaf binders and other known stapling or binding devices and a much higher 'starch of the stack of sheets to be picked up and which also alleviates the difficulties encountered with flexible outer metal

O strip as a pull-up organ, especially with larger thicknesses of the to exclude the sheet staples to be recorded.

This purpose is achieved in that, according to the invention, a bead rod can be inserted and passed through the main holes arranged in the area of the hole zone of the stack of sheets and through a continuation of the main holes in the two support plates enclosing the stack of sheets, and furthermore, the main holes each si ¹¹ laterally Slot in the 'fragile plates, the inlet openings of which are somewhat narrowed in order to

spacers located halfway and below the stack of sheets > O of the bead rod enter the slots with a snap-lock effect to leave and to hold back after inserting and that

- Furthermore, the spacers have a cylindrical shape; knife corresponds to the width of the side slots, while the; Beads are sized so that they cannot be inserted into the slots are. . . -

In a previously known device of a similar type, there is Stringing element made of a rubber rod made of V / calibration rubber, which is attached to his lower end has a stop collar, which is against the Bottom of the stack of sheets lays while he has a head above has, on which a removable head ring can be pushed,

.10 which lies against the top sheet of the paper stack, so that the height of the stack of sheets to a certain distance between the stop collar and the head ring is limited. is If the height of the paper stack is less than or greater than this distance, the aligning element must be replaced by another one of matching Length to be replaced .. Also, the softness must be mentioned 'Parts of the line-up element be relatively large because of the Head ring with a relatively small hole over the stop collar must be forced. For these reasons, the security of the binding of the sheet stack is insufficient. With another, just If a similar stapling device is used, a stick is used which but not directly with the stack of sheets or with support plates works together, but rather by means of things that can be postponed to him Button. Here too, both the pearl rod and the Soft rubber buttons are assumed. To take a single one Leaf of the stack of leaves must remove the buttons from the pearl rods subtracted from. When a large size and weight of the stack of sheets is reached, the binding can easily become ineffective » In addition, the line element consists of two separating elements -> -: - ν.

To make it easier for the beads to pass through the holes 3, it is advisable that these holes have a slightly larger diameter than the largest diameter of the pearls 1 is equivalent to·

further security is achieved in that the emerging Ends of the pearl rods ah the support plates are locked. For this purpose, as shown in FIG. 7 on the support plate 6 Locking element attached a protruding shoulder 12, which is provided with an open slot in which after bending of the bead 7, the spacer 2 in question can be inserted is. Since the outer part of the slot is somewhat narrowed, the spacer 2 engages in the slot with a snap-lock effect a.

In the embodiment according to the year. 6 sits on the support plate an L-shaped arm 13, which with the plate outer surface one Forms slot in which a spacer 2 of the folded bead rod can be inserted with a snap-lock effect, since this Slot is narrowed at its entry end »
