Definitions

  • the present invention relates to the field of office accessories, in particular devices intended for removing staples, for example bundles of sheets, and relates to a method of manufacturing a staple device.
  • the invention also relates to the stapling device 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 fork constitution (see for example US-A-2,624,545).
  • 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 also have a general shape of U, the element carrying the fork with the smallest opening being entirely housed in that carrying the fork with the largest opening.
  • These elements are further provided, externally, over the entire length of their core, each of an overmolded part having, on the side of the forks of the elements, gripping fins.
  • the present invention aims to overcome these drawbacks.
  • a stapling device comprising two elements articulated one on the other at one end by means of an axis and loaded by spring in the direction of separation of their other end, these elements having a general U-shaped section of different dimension and being provided at their free end with hooks, characterized in that it consists essentially in crushing the hooks of the element of larger section, in such a way that these hooks are brought together parallel and penetrate, in the service position, between the hooks of the element of smaller section.
  • the invention also relates to a stapling device obtained by implementing the method described above, characterized in that the hooks of the element of larger section have a crushing such that the external dimension of the fork that they delimit is less than the internal dimension of the fork delimited by the hooks of the element of smaller section.
  • a stapling device which comprises two elements 1 and 2 hinged together. 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 with their free end of hooks 1 ′, 2 ′, and characterized in that it essentially consists in crushing the hooks 1 ′ of 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 service position, between the hooks 2 ′ of the element 2 of smaller section.
  • the invention also relates to a stapling device 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 less than the internal dimension of the delimited fork by the hooks 2 ′ of element 2 of smaller section.
  • the process according to the invention makes it possible, starting from elements 1 and 2 available, moreover, to manufacture stapling devices adapted to other dimensions of staples, without requiring significant investments in tools, a simple additional press tool being necessary to carry out the abovementioned crushing.
  • stapling devices adapted to other dimensions of staples, without requiring significant investments in tools, a simple additional press tool being necessary to carry out the abovementioned crushing.
  • several types of stapling devices can be produced, so that their unit cost price can be reduced.
