DE3934580A1 - Document file locking device - forms beak-type opening at peak to facilitate use - Google Patents

Abstract

The stirrup-type locking device is for a document file. It forms a beak-type opening at the apex. The locking device uses round-section rods or wires (1,2) which are bent into a curve. The ends of two opposed rods abut when the file is closed and the documents are locked in place. The ends of the abutting rods are chamfered so that they overlap. USE - Locking device in file.

Description

The invention relates to a beak-like shape the bow lock with snapping opening, the

• - it allows without repeated actuation of the lock mechanics at different points in the file, the Ring binder or catalog insertions, withdrawals or to be able to carry out exchanges,
• - With the closure tapering towards the mouth arm catches and inserts new sheets.

State of the art

The well-known stapler in folders, ring binders and Catalogs are designed so that the support arm and lock arm form a closed arc for loading or removal with / of file material in full is opened. Should be in different places of the Folder. . . Leaves taken, inserted or out be exchanged, the constant opening and Closing the mechanism as a nuisance.

This deficiency has already been counteracted by Stapler bracket stretched even when closed slanted narrow slit could be taken from the leaves or inserted. Pushing the stack of sheets from the support arm onto the Closing arm and vice versa resulted in this constant Slot opening for hooking and damaging the sheet good.

To remedy this, the constantly open slot is like this been trained that the locking arm at the end with a tongue set off from the outside and the support arm with a pull-out on the outside, the tongue of the clasp on the underside of the domed nose arms overlaps (German Patent 6 97 615 Klas se 11 e group 18 from 6.4.1939). This shape of the constantly open slots between the support arm and the lock poor serves the purpose pursued, but has the disadvantage that the workflow is not fluid enough tet. The insertion of individual new sheets can only by inserting it on the support arm at successor gender overlay across the slit on the clasp poor.  

The disruptive effect of the constantly open slot in Overriding a larger part of the file content from the support arm to the locking arm as well as when returning is not completely resolved.

In the closed position there is no stabilizing ver binding between support arm and lock arm. A warp of the loaded arm compared to the unloaded The closing arm can only be made with particularly strong ones Execution of both the entire mechanics including Avoid substructure as well as the folder.

task

The invention has as its object

• - The constantly open slot through one from the sta cheap, complete closure in partially opening A to replace the gap opening that forms
• - the gap in the upper rounding of the stapler bracket train that from a frontal perspective in shape a wave running cut as inside Shortened closure that stretches on the outside represents poor, who fits the outside shortened, stretched outward spout of the support arms reaching over,
• - by arranging the gap in the upper curve of the stapler bow and reaching over the locking arm the workflow flows more smoothly via the support arm shape.

solution

According to the invention, this object is achieved by

• - That the locking mechanism with a complete before Provide closing tension to be arranged which causes the gap-opening engagement.
• - The in the form of a shaft ( 1 ) gap is arranged in the upper rounding and designed so that the locking arm ( 2 ) with its outside (top) stretched, inside) underside shortened Ausfor formation the outside shortened , on the inside extended support arm.

The latching gap opening allows

• - Documents remaining in the file on the Ver lead to the final point,
• - pull the leaves to be removed through the gap,
• - New or replacement sheets through the gap opening insert,
• - again remain unaffected by filing or exchange to lead the stock across the gap,
• - to continue the replacement process as long as desired,

and without that during the entire process Having to press the locking mechanism again and again. Only at the beginning is the mechanism in the gap opening position and at the end again shut down.

Regardless of this, the wide opening option remains the stapler bracket for more extensive equipment or The folder can be emptied.  

advantage

Compared to the known permanent gap opening opposite course of the slot exist before share in that

• - The gap that only engages during the work process opening closed after completion and so the usual stability of the stapler in the Closing position is reached,
• - The hook and thus injuring the from the arm on the Sheet material to be transferred is not because depending on the amount the material is pulled or Raised outward from the under tongue of the support arm on the locking arm, at rear shift by thrust on the support arm from gentle on the overlapping beak of the locking arm transferred, provided the stapler bracket at the end of the operation has not previously been closed is.
• - The slightly rounded towards the interface running part of the The locking arm catches the perforation from the already turned Position overlaps better and thus facilitates the work process. Therefore, the Lock embossing on the upper interface without hooking resistors negative, on the lower cut surface be raised.
