Abstract

A method for manufacturing a staple-removing device and a device thus obtained. Method consisting essentially in crushing the hooks (1') of the element (1) of larger section, such that these hooks are brought closer together in parallel and penetrate, in an operating position, between the hooks (2') of the element (2) of smaller section.

Description

Method for manufacturing a staple-removing device and device for

  The present invention relates to the field of office accessories, in particular devices intended for removing staples, for example from bundles of sheets, and relates to a method of manufacturing a stapling device.

  The subject of the invention is also the arrangement

stain removal thus obtained.

  The stapling devices known to date are generally in the form of two elements interconnected at one end by means of an axis on which is provided a return spring holding said elements in a position apart from their other

  end, this other end having a consti-

fork tution.

  The forks of the two elements are designed in such a way that the teeth of one can penetrate between the teeth of the other, for example in the shape of a U,

  and the elements carrying said forks have -

  also a general U shape, the element carrying the fork with the smallest opening being fully housed

  in the one with the larger opening fork.

  These elements are provided, moreover, externally, on

  the whole length of their soul, each one piece on-

  molded presenting, on the side of the forks of the elements,

gripping fins.

  These known stapling devices, which are

  generally very effective in achieving any degrafa-

  ge, however, have the drawback of being adapted only to a well-defined staple size, their use for staples of different size, in particular of smaller size, being awkward or even impossible. The use of these devices for larger staples does not generally, moreover, make it possible to obtain good results, the staples being liable to be badly torn off and

thus to tear the paper.

  In addition, the production of devices specially adapted to each size of staples requires

  necessarily the forecast of a large number of

  elements of different dimensions and tools adapted to the manufacture of these elements, so that the price of

  unit returns of said devices is increased.

  The object of the present invention is to alleviate

these disadvantages.

  It has, indeed, for object a process of fa-

  connection of a stapling device comprising two elements articulated one on the other at one end by means of a pin and loaded by spring in the direction

  apart from their other end, these elements pre-

  feeling a general U-shaped section of different dimension

  te and being provided at their free end with hooks,

  characterized in that it essentially consists of

  read a crushing of the hooks of the element of larger section, in such a way that these hooks are brought together in parallel and penetrate in, position of service, between the hooks of the element of smaller

section.

  The invention also relates to a device

  tif stapling obtained by implementing the method described above, characterized in that the hooks

  the element of larger section have a crushing

  such that the outer dimension of the fork

  that they delimit is less than the internal dimension

  - lower fork delimited by hooks

the element with the smallest section.

  The invention will be better understood thanks to the

  description below, which relates to a mode of reaction

  preferred reading, given by way of nonlimiting example and explained with reference to the appended schematic drawing, in which: FIG. 1 is a side elevation view of a device according to the invention, and FIG. 2 is a view in frontal elevation,

  on a larger scale, of the device according to FIG. 1.

  In accordance with the invention, and as my-

  very particularly, for example, the figures

  Figures 1 and 2 of the accompanying drawing, the method of manufacturing a staple device, which comprises two elements 1 and 2 articulated one on the other at one end by means of a pin 3 and loaded by a spring 4 in the direction of separation of their other end, these elements 1 and 2 having a general U-shaped section of different size and being provided at their free end with

  hooks 1 ', 2', and characterized in that it consists

  essentially to crush the hooks 1 ′ of the element 1 of larger section. This crushing is carried out in such a way that the hooks 1 'are brought together in parallel and penetrate, in the position of

  service / between the hooks 2 'of element 2 more small-

this section.

  The invention also relates to a device

  tif stapling whose hooks 1 'of the element 1 of larger section have a crushing such that the external dimension of the fork which they delimit is

  smaller than the inside dimension of the fork

  mitée by the hooks 2 'of the element 2 of smaller section. The method according to the invention makes it possible, starting from elements 1 and 2 available, moreover, to

  manufacture staple devices suitable for other

  very staple dimensions, without requiring significant investment in tools, a simple press tool

  being necessary to carry out the crushing

  mentioned above. Thus, starting from a minimum of basic elements, several types of stapling devices can be produced, so that their cost price

unit can be decreased.

  The economy of basic elements is also expanding

  ment to overmolded parts 5 and 6 fitted respectively-

  elements 1 and 2 and provided with pre-

  hension 5 'and 6'. Indeed, due to the maintenance of the general section of the elements 1 and 2 and the simple transformation of the hooks 1 'of the elements 1, these molded parts 5 and 6 remain perfectly adaptable

  to said elements 1 and 2, so that over-molded parts

  specific information is not required.

  The invention is not limited to the mode of realization

  reading described and shown in the accompanying drawing. Mo-

  modifications remain possible, particularly from the point of view

  of the constitution of the various elements or by substitution-

  tion of technical equivalents, without going out

  of the protection field of the invention.
