Definitions

  • the present invention relates to a stationery accessory, and in particular relates to a stationery accessory which is configured to be attached to a stack of sheet articles, such as a stack of sheets of paper, by means of a staple.
  • the stationery accessory is also configured to remove the staple from the stack of sheet articles.
  • a stapler generally comprises a lower arm pivotally connected at one of its ends to a corresponding end of an upper arm such that the free ends of the arms are in spaced apart opposition.
  • the free end of the lower arm has an anvil which is in opposition to a delivery head located at the free end of the upper arm.
  • the upper arm carries a cassette of staples which are spring loaded against the delivery head.
  • the cassette of staples comprises an inverted, flat-bottomed U-sectioned channel with a plurality of frangible sections, each of which defines a staple.
  • the stack is placed between the free ends of the arms of the stapler such that the lowermost sheet of the stack lies adjacent the anvil and the uppermost sheet of the stack lies adjacent the delivery head.
  • the frangible section at the end of the cassette becomes separated from the rest of the cassette to define a staple.
  • the staple therefore comprises a thin element having a substantially flat base and two downwardly projecting puncture arms. Further downward motion of the upper arm drives the free ends of the puncture arms of the staple through the stack of sheets until the free ends of the puncture arms engage with recesses in the anvil which bend the arms outwardly or inwardly such that they lie generally parallel with the lower most sheet of the stack.
  • a staple it is usual for a staple to be stapled through the top left hand corner of a stack of sheets to facilitate the folding of the sheets over the base of the staple to view the sheets below. It is to be appreciated that the stapler mechanism by which the staple is applied to a stack of sheets may vary, but the end result is generally the same.
  • general handling of a stapled stack of sheets may cause the sheets to move relative to each other such that the holes made through the sheets by the staple become enlarged, resulting in a reduction in the security of the staple fastening.
  • a stationery accessory such as a staple remover to remove a staple from a stack of sheets.
  • a staple remover typically comprises a pair of arms which are pivotally connected together at one end and which have opposing teeth at their free ends.
  • the teeth on each arm have a wedge profile which starts at a point at the free end of the arm and which tapers away towards its arm in the direction of the pivot. When the arms are brought together, the opposing teeth overlap each other.
  • the points of the teeth are brought together between the base of the staple and the uppermost sheet such that further motion of the arms towards each other causes the base to be drawn away from the points of the teeth in the direction of the pivot along the intersection of the wedge profiles, and hence away from the top sheet of the stack.
  • the free ends of the puncture arms are therefore bent straight as they are withdrawn through their respective holes in the stack of sheets, enabling the staple to be removed from the stack of sheets.
  • the disadvantage of using such a staple remover is that not only is the staple remover not always conveniently available when needed, it can sometimes be difficult to engage the teeth between the base of the staple and the uppermost sheet which can cause damage to the uppermost sheet of the paper. Furthermore, removal of the staple from the stack can also cause damage to the lowermost sheet of the stack as the free ends of the puncture arms are withdrawn through the stack.
  • a stationery accessory comprising:
  • the second element has sufficient strength to resist damage by the staple when the staple is removed from the second element.
  • At least the first element is flexible.
  • both the first and second elements are flexible.
  • the first and second elements are connected to one another.
  • connection defines an elongate abutment portion, such that when the stationery accessory is in the in-use position a first edge of each sheet article in the stack of sheet articles abuts the elongate abutment portion.
  • a locating abutment portion is provided on at least one of said elements, such that when the stationery accessory is in the in-use position a second edge of each sheet article in the stack abuts the locating abutment portion, and wherein the second edge is orthogonal to the first edge.
  • the first and second elements are hingedly connected to one another.
  • the first and second elements are connected by a living hinge.
  • the stationery accessory is formed of a plastics material.
  • At least the first element has a gripping formation, said gripping formation being configured to be gripped by a user so as to facilitate said pulling of the first element away from the uppermost sheet of the stack.
  • the second element is also provided with a gripping formation.
  • the or each gripping formation takes the form of a tab.
  • the or each tab has a gripping projection.
  • the or each tab is connected to the respective element by a hinge.
  • the or each tab is connected to the respective element by a living hinge.
  • the or each gripping formation is spaced from the connection between the first and second elements.
  • the stationery accessory is provided with indicia.
  • the first and second elements are substantially planar.
  • the stationery accessory is provided with a label.
  • the stationery accessory is provided on the corner of a stack of sheet articles when in the in-use position.
  • the upper element 2 has a similar triangular profile to that of the lower element 3, the upper element having a pair of orthogonal side edges 7, 8 and an hypotenuse edge 9.
  • the upper element 2 is superimposed above the lower element 3 and is spaced from the lower element 3.
  • connection formation 10 which spaces the upper element 2 from the lower element 3 such that the planes of the upper and lower elements 2, 3 are, at least initially, substantially parallel.
  • connection formation 10 is preferably formed integrally with the upper element 2 and lower element 3, and comprises an element of substantially uniform thickness which extends in an arc from the edge 4 of the lower element 3 to the corresponding edge 7 of the upper element 2 such that the respective inner surfaces of the upper element 2 and lower element 3, and the connection formation 12 together define a channel 11 with substantially parallel sides.
  • the inner surface of the connection formation 10 defines an elongate abutment portion 12.
  • connection formation 10 defines a hinge 13 whose axis extends parallel with the upper and lower edges 4, 7, and along the centre of the connection formation 10.
  • the hinge 13 is preferably a living hinge which comprises a section of reduced thickness. Therefore, the space between the elements 2, 3 can be increased or decreased.
  • a gripping formation in the form of a substantially planar tab 14.
  • the tab 14 is hingedly connected to the upper element 2 by means of a hinge 15 whose axis is coincident with the hypotenuse edge 9.
  • the hinge 15 is preferably a living hinge, which enables the tab 14 to be moved about the axis of the hinge 15. As can be seen from figure 1, because the tab 14 is formed along the hypotenuse edge 9, it is spaced from the connection formation 10.
  • the stationery accessory 1 is preferably made from a plastics material which is suitable for puncture by a staple as will be described in more detail below. Also, a preferred embodiment is formed such that the upper and lower elements 2, 3 are flexible.
  • FIG. 3 the above-described stationery accessory is shown mounted in position on a stack of sheet articles.
  • the upper element 2 is positioned adjacent an uppermost sheet 19 of the stack 17 and the lower element 3 is positioned adjacent a lowermost sheet 20 of the stack 17.
  • the space between the elements 2, 3 can be increased or decreased sufficiently to allow stacks of different thicknesses to be inserted between them.
  • the hinge 13 is provided with a degree of inherent resilience to bias to upper and lower elements towards one another.
  • a staple 21 generally comprises a base 22 having two downwardly projecting puncture arms 23 which are configured to be driven through a stack of sheets which require stapling.
  • the free ends of the puncture arms 23 can be driven simultaneously in sequence through the upper element 2, through the stack 17, and then through the lower element 3 to secure the staple 21 to the stack 17 as illustrated in figure 3.
  • the upper and lower elements 2, 3 abut a greater area of the uppermost and lowermost sheets 19, 20 of the stack 17 than the area which would be abutted only by a staple 21 (i.e. without the stationery accessory also being secured to the stack 17), the likelihood of tearing, or detachment of the uppermost and lowermost sheets 19, 20 from the stack 17 due to general handling of the stack 17 may be reduced.
  • the stationery accessory 1 also has a second function.
  • the tab 14 can be bent away from the uppermost sheet 19 about the tab hinge 15 to enable both sides of the tab 14 to be gripped between the fingers of the user.
  • Figure 4 shows that as the user pulls on the tab 14 in a direction generally away from the uppermost sheet 19, the upper element 2 is moved away from the uppermost sheet 19 of the stack 17 such that the upper element 2 pivots about the hinge 13 and the space between the upper and lower elements 2, 3 is increased. The consequence of this is that the upper element 2 bears against the base 22 of the staple 21 and withdraws the staple 21 from the stack 17.
  • the staple 21 and the stationery accessory 1 can be conveniently removed from the stack 17 in a simple manner, without the need for any additional tool to remove the staple.
  • connection formation 10 facilitates the pulling of the upper element 2 away from the uppermost sheet 19, and provides sufficient leverage to withdraw the staple 21 from the stack 17.
  • the material of the upper element 2 should possess sufficient strength to resist substantial deformation by the base 22 of the staple 21 as it is being pulled away from the uppermost sheet 19 of the stack 17 so that the staple 21 can be removed from the stack 17.
  • the material of the lower element 3 should possess sufficient strength to resist damage to the respective puncture holes as the free ends of the puncture arms 23 of the staple 21 are being withdrawn through them. This is to prevent the holes from becoming enlarged, or the area surrounding the holes from becoming deformed to the extent that damage is caused to the lowermost sheet 20 of the stack 17 as the staple 21 is being removed.
  • FIG 5 there is illustrated an alternate embodiment of stationery accessories.
  • the same reference numerals are used for this embodiment to identify features which correspond to features of the first embodiment illustrated in figures 1 to 4.
  • a stationery accessory which is similar to that of the first embodiment in that the upper element 2 generally has a triangular plan profile but differs in that the hypotenuse edge 9 is not straight but curved.
  • a generally planar tab 14 is provided which is of triangular form and which is hingedly connected to the upper element 2 in an apex region between the side edge 8 and hypotenuse edge 9, the axis of the hinge 15 of the tab 14 lying parallel with the side edge 7 and hence with the hinge 13 of the connection formation 10.
  • FIG 6 there is illustrated a further embodiment of stationery accessory which differs from the one illustrated in figure 5 in that the hypotenuse edge 9 extends all of the way from the side edge 7 to the side edge 8 in a generally sinusoidal curve, and that the tab 14 has a plan profile which defines the apex between the side edge 8 and the hypotenuse edge 9. Furthermore, the tab 14 is provided with a series of gripping projections 24 to provide an improved gripping surface for the user when the tab 14 is being gripped by the user to pull the upper element 2 away from the uppermost sheet 19 of the stack 17.
  • both the upper and lower elements 2, 3 have a substantially semi-circular profile.
  • this profile is defined by side edge 25 and an arcuate edge 26 which extends between the ends of the side edge 25.
  • Figure 7 shows that this embodiment of stationery accessory can be placed in its in-use position along any side edge of the stack 17.
  • the upper element 2 is not provided with a tab, but the material of the upper element 2 is sufficiently flexible that when the stationery accessory 1 is in the in-use position and stapled to a stack of sheets 17, the user can lift the upper element 2 away from the uppermost sheet 19 of the stack 17 by placing a fingernail under the arcuate edge 26 of the upper element 2 and then grip the upper and lower surfaces of the upper element 2 between his or her other fingers to pull the upper element 2 away from the uppermost sheet 19.
  • stationery accessory illustrated in figures 1-6 could be provided with a locating abutment portion on either the upper element 2 or the lower element 3.
  • the locating abutment portion would take the form of a projection, or lip, upstanding from the inner surface of the element such that when the stationery accessory is in the in-use position, the edges 18 of a first side of the stack 17 abut the elongate abutment portion and the edges 18 of a second side of the stack 17 abut the locating abutment portion, thus ensuring accurate location of the stationery accessory 1 on the corner of the stack.
  • stationery accessory can be provided with surface indicia or labels as a means of identification.
  • a label may be stuck to the lowermost element 3 over the free ends of the puncture arm 23 as a security measure. If the stationery accessory were to be used to remove the staple from the stack 17, then the label would become damaged indicating that the stack of sheets 17 has been tampered with. A supply of such labels could be supplied in combination with the stationery accessory.
