Definitions
- This invention relates to a device of the kind for attaching together sheets of paper, plastics and similar materials solely by interengagement of the materials of the sheets. It also concerns apparatus for simultaneously perforating and attaching together sheets.
- Swiss patent specification 674,727 describes a hand-held device for attaching documents together, having two pivoted levers on opposite sides of a central body having a slot for receiving the documents.
- the upper lever carries a pivoted cutter one end of which cuts tongues in the sheets and the other end cuts a slit.
- a pusher is carried by the lower lever for pushing the tongues through the slits after retraction of the upper lever and the cutter.
- US patent No. 3,577,575 describes a device for binding sheets of paper having a base on which there is a pivoted member carrying two cutters.
- One cutter is a fixed U-shaped piece designed to cut tongues in the sheets when the movable member is moved down.
- the second cutter is designed to pass down through the paper to cut a slit, receive in an aperture the tongues folded on the other side and, when the movable member is moved back up, pull the tongues through the slits and thereby attach the sheets together.
- the tongues are pushed down, folded back under the sheets and thrust through the eyelet by a pawl carried by a cam pivotally mounted on the first cutter which is fixedly mounted on the first member.
- the pawl When the pawl is fully pivoted, its end projects into the aperture in the second cutter, driving with it the tongues. In operation, there is a risk that the tongues may frequently be ripped, thereby damaging the documents and jamming the device. There is also a risk of the pawl jamming in the aperture of the second cutter.
- the device is thus complicated and its operation is not reliable. Furthermore, the device is designed only to rest on a supporting surface, which limits its possible uses.
- An object of the invention is to provide a simple and reliable version of the last mentioned type of device for attaching together sheets of paper, plastics and similar materials solely by interengagement of the materials of the sheets.
- a device of the type defined in the pre-characterising part of claim 1 is characterised in that : the first cutter is pivotally mounted for cutting and folding the tongues, the first cutter having a leading cutting edge for cutting the free ends of the tongues and initiating folding of the tongues, and a trailing edge adjacent the attached ends of the tongues for folding the tongues into said aperture ; and means are provided for pivoting the first cutter as the first member reaches the closed position while said trailing edge has moved part way down the tongues, the first cutter being spaced apart from the second cutter and remaining spaced from the second cutter during pivoting of the first cutter.
- the device In operation, upon pivoting of the first cutter, its trailing edge pushes an intermediate part of the tongues to fold the tongues about their attached ends until the free ends of the tongues project into said aperture in the second cutter without penetration of the first cutter in said aperture.
- the device thus employs a pivoted first cutter that provides both functions of cutting and folding the tongues but does not protrude into the path of the second cutter and therefore cannot impede movement of the second cutter.
- first and second members of the device are pivotally connected together, the first member comprising an upper lever carrying the first cutter and the second cutter, and a lower lever having an abutment forming part of the pivoting means for the first cutter.
- These upper and lower levers are pivotally mounted together for limited relative movement between (a) a rest position, (b) an intermediate pushed-in position and (c) a fully pushed-in position, in which, respectively :
- a spring or other means may be provided for biasing the first member to the open position and another spring or other means is provided for biasing its upper lever to the rest position.
- These biasing means are preferably so arranged that when the upper lever is pressed in, firstly the entire first member pivots until the lower lever is arrested by the second member, then the upper lever pivots to its intermediate and fully pushed-in positions.
- the first cutter has two arms at an angle to one another, for instance about a right angle, the first arm carrying an oblique cutting surface between the leading and trailing edges, and the second arm having a part which abuts against said abutment surface of the lower lever, for instance a downward projection that abuts against an upper surface of the lower lever, or an end part of the second arm abuts against an upstanding projection on the lower lever.
- the first cutter is preferably biased to a rest position by a spring.
- the second member of the device usually has has a flat bottom surface so the device can rest on a generally flat support, and may be operated while it is resting on a support.
- the device is preferably a small hand-held device adapted for operation while being held in a hand. Whether operated in the hand or when resting on a support surface, the device is very convenient to use because its handling is quite similar to well known staplers.
- the device of any desired shape, e.g. as a promotional item in the shape of an emblem or design to be promoted, and/or with its upper surface or sides shaped to receive specific advertising materials.
- first cutters with associated second cutters and means for pivoting the first cutters, the first cutters being arranged for simultaneously cutting and folding tongues at a plurality of discrete locations.
- first cutters having a common pivoting axis could be placed side-by-side facing two corresponding side-by-side second cutters, so as to simultaneously cut two tongues in spaced parallel relationship.
- two first cutters could be arranged back-to-back for pivoting in opposite directions towards respective second cutters. In this case, two tongues would be cut in alignment with one another.
- the invent ion also provides an apparatus for perforating and simultaneously attaching together sheets of paper, plastics and similar materials comprising at least two devices as set out above. These devices are spaced apart from one another and adapted and arranged to receive an edge part of superposed sheets to be attached and to cut tongues at locations spaced from one another along said edge part leaving corresponding perforations at these locations, i.e. in the edge part of the sheets adjacent the folded attached ends of the tongues.
- two devices can be mounted side-by-side in a combined perforator/attaching device producing generally square or rectangular perforations adapted to cooperate with a conventional ring binder or other document filing system.
- the device may optionally include means for embossing the attached sheets preferably in the area where the tongues are folded over.
- the first and second members can carry complementary matrices that produce a distinctive embossment or seal on the attached sheets and at the same time reinforce their attachment.
- the tongues cut in the sheets, and the corresponding perforations left in the attached sheets are usually generally rectangular but may also be of generally trapezoidal shape for example with the free end wider than the attached end about which the tongues are folded. Other shapes of tongues and perforations are possible.
- the slit or similar opening cut in the sheets by the second cutter usually has a length about equal to the width of the free end of the tongues, but it can be narrower so that the free end of the tongues must be bent as it is inserted through the slit. This is preferred if the tongues are of trapezoidal or other shape with an enlarged free end.
- the device according to the invention has many uses. It is intended mainly for connecting together a few sheets and can be used in offices for attaching together several documents, especially documents that may need to be destroyed in a shredding machine. It can also be used for closing paper or plastic bags, e.g. at supermarket outlets, or for attaching receipts. This is particularly important for packaged foods, where metal staples could be dangerous. Further uses include attaching large sheets or webs along their sides and for attaching display cards to goods packed in plastic or paper sheets. Also, as mentioned above, the device can be used to simultaneously perforate and attach documents to be filed.
- the device illustrated by way of example in Figures 1 to 4 is suitable for attaching together sheets 1 of paper, plastics and similar materials solely by interengagement of the materials of the sheets 1.
- tongues 2 each having a free end 3 and an attached end 4 are cut in superposed parts of the sheets 1 by the device, and are folded and pushed through slits 6 in the sheets 1 to interlock and hence attach the latter, the slits 6 being spaced from the attached ends 4 of the tongues 2 by a distance D which is less than the length L of the tongues 2 and the corresponding perforations 5.
- the device has a first member 10 pivotally mounted on a second member 20.
- First member 10 is made up of an upper lever 11 of inverted U cross-section and a lower lever 12 of U cross-section, with lever 11 fitting into lever 12.
- member 20 has a pair of side plates 21 in which the levers 11 and 12 are pivotally mounted about a common pivot 22 situated at about the level of the upper face of member 20.
- the upper lever 11 Towards its free end, the upper lever 11 carries internally a pivotally-mounted first cutter 30 for cutting and folding the tongues 2 and a second cutter 40 for cutting the slits 6.
- Members 10 and 20 are shown in Fig. 1 in an open position, towards which they may be biased for example by means of a spring such as a blade spring (not shown) located between member 20 and lever 12 adjacent pivot 22.
- a spring such as a blade spring (not shown) located between member 20 and lever 12 adjacent pivot 22.
- the open position it is possible for the open position to be defined by indents in the side plates 21. In this open position, sheets 1 to be connected can be placed in a gap 18 between the bottom surface of lever 12 and the upper surface of member 20.
- the first cutter 30 is lodged in a recess 13 in upper lever 11 to which it is pivoted about a pivot 31.
- Cutter 30 has two arms 32 and 33 approximately at right angles to one another. Arm 33 is generally horizontal and, in the illustrated example, has a downwardly-projecting end 34. Arm 32 projects downwardly and has a lower, leading cutting edge 35 and a trailing edge 36 joined by an oblique cutting surface 37. The trailing edge 36 points in the direction of the downwardly-projecting end 34 and is facing but spaced apart from the second cutter 40.
- Cutter 30 is biased to a rest position, as in Figure 2, with its arm 32 in contact with a generally vertical surface of recess 13, by means of a compression spring 38 acting between arm 33 and a recess 14 in lever 11.
- the second cutter 40 is a fixed knife having a downwardly-projecting blade 41 with a pointed lower cutting edge 42 and an opening 43 ( Figure 4) for receiving tongues 2.
- the side edges of wall 41 may be bent at right angles to the plane of Figure 4.
- Cutter 40 is secured to the upper lever 11 by screws 44.
- the lower lever 12 has an opening 19 for passage of the cutting arm 32 of cutter 30. Adjacent the opening 19, the upper surface of lever 12 forms an abutment 17 for cooperation with the end 34 of cutter 30, as described below. Also, in the upper surface of member 20 is a recess 24 for receiving the cutters 30, 40 during operation.
- the recess 24 is preferably a cruciform slot having a main part just wide enough to receive the first cutter 30, and a transverse part for receiving the edges of second cutter 40.
- Levers 11 and 12 are pivotally mounted together for limited relative movement between a rest position, shown in Figure 1, an intermediate pushed-in position shown in Figure 2 and a fully pushed-in position shown in Figure 3.
- levers 11 and 12 are for example limited by means of an internal groove, about mid-way along the inside of one of the sides of lever 12, receiving a pin carried by lever 11.
- Lever 11 is biased to the rest position by means of a compression spring 16 having one end lodged in a recess 15 in lever 11 and its other end acting against the inside of the bottom of lever 12.
- cutter 30 is pivoted by abutment 17 whereby its trailing edge 36 thrusts the tongues 2 into aperture 43.
- This fully pushed-in position is reached when lever 11 is fully pressed down beyond the intermediate position.
- Member 20 has a flat bottom 23 by which it can be placed on a flat supporting surface, while the device is at rest.
- the device can be operated while it rests on a supporting surface, but is so dimensioned that it can easily be held in a single hand and operated by a single hand while being held.
- Sheets 1 to be attached are placed in gap 18 with the device in its rest position. The user then simply presses the members 10 and 20 together. In the first part of the movement, the sheets are pressed between member 20 and lever 12 and the movement of lever 12 is arrested. The sheets are thus firmly held for the subsequent cutting and folding operations.
- tongues 2 are cut in the sheets 1 by the leading edge 35 and oblique cutting surface 37 of cutter 30, and slits 6 are cut by the cutting edge 42 of cutter 40.
- the cutter 30 does not pivot, but folding of the tongues 2 is nevertheless initiated by surface 37.
- the tongues 2 are at an approximately vertical position and the trailing edge 36 has already begun to move part way down the folded tongues.
- the trailing edge 36 moves abruptly to the right (looking at the drawings) and folds the free ends of tongues 2 into the opening 43. This is accomplished without the edge 36 penetrating into opening 43. There is thus no risk of jamming.
- the described device is simple, convenient to use and can be used repeatedly without a need to recharge it with any external attaching elements.
- the device can be made entirely or partly of suitable plastics materials.
- the first and second cutters 30, 40 can be made of metal or hard plastics materials such as Delrin®.
- the levers 11, 12 and member 20 can each be made of single moulded pieces or several connected parts leaving suitable internal cavities for the operating mechanism. Instead of being generally parallel to the members 10, 20, the first cutter(s) 30 and hence the tongues 2 could be transverse to these members. Also, the projection 34 extending down from cutter 30's arm 33 could advantageously be replaced by a pin or other piece projecting up in the place of abutment 17.
