Definitions

• the height of the slide is designed for relatively high staples and there is nothing to prevent staples of several different heights, this choice being dictated by the thickness of the products to be assembled.
• the staples are constantly pushed by a spring towards a stop located a small distance beyond the front end of the slide, this small distance corresponding, to a small play close to the thickness, to the thickness of a clip.
• the first staple of a line is in longitudinal abutment, above a guide overhanging an "anvil” and below a movable pusher.
• the guide itself must have dimensions corresponding to those of the staples to avoid jamming.
• Office mail is very often made up of letters two or three pages long, with or without an attachment, while documents such as quotes, contracts, briefs, etc. can reach fifty pages.
• Staplers are tools that are not only used for office activities but also in commerce and industry.
• the present invention provides a solution to this problem and, for this purpose, relates to a stapler, of the type comprising:
• a pusher mounted movable perpendicular to the staples
• REPLACEMENT FIRE Means of approximation and spacing of the pusher and the anvil
• the staple storage and pushing assembly comprises at least two superimposed slides, of different widths, for clips of widths coordinated with those of the slides, push button which is associated with a guide adapted to the dimensions of said push button and which is located above another guide intended to receive staples of all widths and having, for this purpose, a width corresponding to those of the largest staples.
• the slides are mounted movable relative to each other and are associated with relative displacement means comprising an operating member accessible from the outside.
• the means for relative movement of the slides comprise, for each slide, a slide that must cooperate with drive parts integral with an operating wheel.
• FIG. 1 is a schematic sectional view of a stapler according to the invention in the rest position and prepared for the installation of staples of a first caliber.
• FIG. 2 is a schematic sectional view of the stapler of Figure 1 in the position of installation of a staple of the first caliber.
• FIG. 3 is a schematic sectional view of a stapler according to the invention in the rest position and prepared for the installation of staples of a second caliber, greater than the previous one.
• REPLACEMENT FIRE (RULE 26) - Figure 4 is a schematic sectional view of the stapler of Figure 3 in the position of installation of a staple of the second caliber.
• FIG. 5 and 6 are schematic perspective views of two clips respectively of the first and second caliber.
• FIG. 7 is a partial schematic view in cross section, taken along the line VII - VII of Figure 1
• FIG. 8 is a partial schematic view in cross section, taken along line VIII - VIII of Figure 1
• FIG. 9 is a schematic overview of a stapler according to the invention.
• a stapler in accordance with the invention is produced here in the form, well known per se, of a clamp having two jaws 1 and 2 articulated together by a pivot 3.
• the Jaw 1 is integral with a control lever 4 arranged in opposition to a second control lever 5, which has a light in an arc of a circle 6 in which the pivot 3 extends and whose end 7 opposite to the second lever 5, carries a pawn 8.
• This pin 8 is engaged in a slot of a pusher 10 mounted to slide, so that the relative movement between the levers 4 and 5 has the consequence, at the end of the tightening stroke, that the pusher 10 is driven towards the jaw 2 which carries an anvil 1 1.
• the stapler can be used for two sizes of staples, this size being considered not with respect to the length of the branches, that is to say at the height H of the staples, but screws -with respect to width L and thickness E of the staples ( Figures 5 and 6).
• the stapler has a set 20 for storing and pushing the staples which comprises two superimposed slides 21 and 22, each of them being adapted to a caliber of staples and carrying a series of staples A1 and A2 respectively.
• Each of the two slides 21 and 22 is movable relative to the other and can be selected to be placed either in the active position while the other is in the neutral position, or in the neutral position while the other is in the active position.
• the selected slide In the active position, the selected slide is in the advanced position, the first of the staples A1 or A2 that it carries being in abutment in line with the pusher 10, the other slide then being in the retracted position.
• the pusher 10 and the anvil 11 are unique because they are suitable for the two sizes of staples A1 and A2.
• the first clip in a series whatever its caliber, and therefore whatever the slide selected, is located above a clip guide 23 whose section is adapted to the dimensions of the clip A2 of higher caliber.
• the pusher 10 is associated with a guide 24 formed by two distinct elements, namely a plate and a roller whose spacing is equal, to within a small clearance, to the thickness of the pusher 10.
• REPLACEMENT HALF (RULE 2b;
• the stapler can therefore be used for two kinds of staples A1 and A2 but has a single pusher 10 and a single anvil 11.
• a flywheel 30 is provided here which is pivotally pivoted along an axis perpendicular to that of the slides 21 and 22 and secured to two eccentric pins 31 and 32.
• the pin 31 is engaged in an oblong slot in a slide 33 secured to the slide 21 and the pin 32 is engaged in an oblong slot in a slide 34 secured to the slide 22.
• the slide 21 is put in the active position and the slide 22 in the rest position, which corresponds to the positioning of the staples A1 (FIGS. 1 and 2), while in the second case, the slide is put 21 in the rest position and the slide 22 in the active position, which corresponds to the positioning of the staples A2 (FIGS. 3 and 4).
• the flywheel 30 has two balls 35 and 36 located in two wells 37 containing springs of thrust 38, the lower part of the jaw 1 having two housings in which the balls 35 and 36 are pushed by the springs 38.
• the ball 35 In a given position of the slides 21 and 22, the ball 35 is located towards the front of the stapler and the ball 36 towards the rear ( Figures 1 and 2), while in the other position of the slides 21 and 22 , the ball 35 is located towards the rear of the stapler and the ball 36 towards the front ( Figures 3 and 4). It is easy to pivot the steering wheel 30 voluntarily because it suffices to overcome the thrust force of the springs 38.
• staples A1 the width of which is 9 millimeters and staples A2 the width of which is 12 millimeters.
• Their thickness E can vary from 0.3 to 0.8 millimeters, for a pusher 10 whose thickness is 0.7 millimeters.
• the height H of the staples can also vary but this is not new in itself since this is already common practice: the slide receiving the staples is given a height equal to the maximum possible height for the staples, all the lower heights being automatically acceptable.
• each slide 21-22 is associated with a mechanism of known type comprising a staple plunger permanently biased by a spring 25 and 26 respectively, each series of staples thus being completely autonomous.
• the number of different kinds of staples can be greater than two, as long as one remains within the acceptable limits for guiding the staples towards the anvil 11.
