Definitions
- the present invention relates to a stapler comprising an elongated magazine shaped to receive back width staple strips included in a determined width range, magazine cover secured to a rail and movable between a first position, where it gives access to the charger, and a second position in which the rail passes between the legs of a staple strip installed in the feeder to guide these towards an actuatable striker for detach and plant the head clip of the tape in a final support.
- FR-A-2 568 813 another stapler designed to accept staples of different sizes.
- This includes an elongated magazine or charger comprising two U-shaped profiles connected by a member central support serving as rail for staples.
- the two profiles have different widths. One is narrow, to enclose tightly one of the branches, or legs, of a staple. The other is wider so that it can accommodate the other staple tab, regardless of the back width of this one, as long as the latter is all even within a range of predetermined widths.
- the installation of a strip of staples on such a rail requires some attention because part of the strip must be enclosed in a U-shaped profile of narrow width, barely greater than the thickness of the wire making up the thickest staples that can receive the stapler.
- the object of the present invention is to provide a stapler of the type described in the preamble to this description, which has none of the drawbacks mentioned above and which therefore allows the implementation place, without special precautions, a battery or strip of staples whose back width can vary in a predetermined area.
- this lateral displacement allows close guidance of the staple strip in the feeder, regardless of the back width of the tape staples, as long as this width is included in the range of predetermined widths.
- the stapler according to the invention comprises essentially a handle 1 and a lever 2 that we takes charge to arm and trigger, conventionally, a striker 3 suitable for detaching the head clip from a strip or stack of such staples 4 installed in a magazine 5 for the stapler.
- An elastic organ (not shown) pushes the staple strip in the direction of the arrow F, against a stop defining the position of the tape head clip, to the right of the striker 3. All these provisions are well known and do not require not a more detailed description.
- FIGS. 2 to 5 of the appended drawing in which the magazine 5 of the stapler according to the invention is shown diagrammatically.
- the magazine 5 of the stapler according to the invention takes the form of an elongated channel, of rectangular section for example, closed by a cover 8.
- the cover 8 takes the form of a slide.
- the channel has a bottom 6 1 and lateral flanks 6 2 , 6 3 . These are hollowed out by two grooves 7 1 , 7 2 in which the slide 8 slides on which a U-shaped rail 9 is fixed, parallel to the large dimension of the slide.
- the staples such as the staple 10 i of a strip 4 of n staples (i from 1 to n) are mounted astride the charger, on the rail 9.
- the stapler according to the invention is capable of receiving staples of different back widths and, possibly, of different thicknesses.
- FIGS. 2 and 3 show staples 10 i and 11 i with widths l 1 and l 2 and thickness e 1 and e 2 respectively, these staples having the extreme widths of a predetermined range of widths acceptable by the stapler.
- the stapler can thus accept staples of widths varying between 10.57 mm and 11.53 mm, a variation of almost 10% of the width of the staples.
- the width of the slide 8 is less than the distance between the bottoms of the grooves 7 1 , 7 2 in which this slide slides. This arrangement allows the slide, and the rail 9 which it supports, to pass from the position shown in FIG. 2 to that shown in FIG. 3, and vice versa, for the purpose explained above.
- the head staple is perfectly placed under the striker 3, in a plane perpendicular to the axis of the rail. To do this, it is necessary that at least on one side, for example that facing the flank 6 2 of the loader 5, the strip of staples 4 is guided closely between the rail and this flank, as shown in FIG. 3.
- This object of the invention is achieved by passing the rail 9 from a substantially central position in the charger, shown in Figure 2, in the position side shown in Figure 3.
- FIG. 2 The central position illustrated in FIG. 2 allows the rail to pass between the tabs of the staples, whatever their width (between 1 1 and l 2 ) and whatever the side, 6 2 or 6 3 , of the charger on which the strip is supported.
- the lateral position illustrated in FIG. 3 defines a narrow channel between the rail 9 and the sidewall 6 2 of the loader, for example, of width slightly greater than the thickness of the thickest admissible clip.
- the axis of the strip of staples remains substantially parallel to that of the rail, which makes it possible to present the head staple exactly to the right of the striker 3, itself constituted by a movable blade in a plane perpendicular to the rail axis.
- FIG. 4 There is shown in broken lines, in FIG. 4, the position of the slide 8 and of the rail 9 after the latter began to engage between the legs of the staples a strip of staples 4, the head staple of which is stop under the striker 3, by the thrust of the member elastic mentioned above, symbolized by the arrow F, and mounted on rail 9.
- the width R of the rail must be such that: R ⁇ 21 2 + 2nd 2 - VS C being the width of the magazine, l 2 and e 2 the back width and the thickness of the smallest admissible staple, respectively.
- the thicknesses e 1 and e 2 to satisfy the following relationships:
- cam means provided at the ends of the grooves 7 1 , 7 2 , and of the slide 8, as shown in FIGS. 4 and 5.
- These cam means comprise cams 12 1 , 12 2 proper formed at the two ends of the slide 8, on two opposite edges of the latter, these cams projecting from these edges with the same thickness, equal to the calculated offset.
- the cams 12 1 , 12 2 cooperate with counter-cams 13 1 , 13 2 respectively, formed at the bottom of the grooves 7 1 , 7 2 respectively, at two opposite ends thereof.
- these grooves comprise cams 14 1 , 14 2 , of the same height as the aforementioned cams and counter-cams, which cooperate with the straight edges 15 1 , 15 2 opposite the slide 8 to maintain the parallelism of the axes of the slide 8 and of the loader 5, when the latter is closed by the slide.
- This parallelism ensures the correct positioning of the clips under the striker 3, in a plane perpendicular to its axes.
- the present invention achieves the goal, namely to ensure placement of staples of variable width in the stapler magazine, without special precautions and this while ensuring good guidance of all strip of staples, from the smallest to the widest, in the extent that the dimensions of these staples are linked by relations (2) and (5) above.
- the invention is not limited to the mode described and depicted as an example. This is how this invention can be easily adapted to a charger on which the rail is hinged rather than mounted on sliding.
Description
La présente invention est relative à une agrafeuse comprenant un chargeur allongé conformé pour recevoir des bandes d'agrafes de largeur de dos comprise dans un domaine de largeurs déterminé, un couvercle de chargeur solidaire d'un rail et mobile entre une première position, où il dégage un accès au chargeur, et une deuxième position dans laquelle le rail passe entre les pattes d'une bande d'agrafes installée dans le chargeur pour guider celles-ci vers un percuteur actionnable pour détacher et planter l'agrafe de tête de la bande dans un support final.The present invention relates to a stapler comprising an elongated magazine shaped to receive back width staple strips included in a determined width range, magazine cover secured to a rail and movable between a first position, where it gives access to the charger, and a second position in which the rail passes between the legs of a staple strip installed in the feeder to guide these towards an actuatable striker for detach and plant the head clip of the tape in a final support.
On connaít de telles agrafeuses, conçues pour recevoir des agrafes de tailles différentes, par exemple l'agrafeuse référencée ROCAFIX MS 10 dans les catalogues de la société française Sofragraf Industries. Dans les instructions qui sont données pour l'installation d'une bande rectiligne d'agrafes dans le chargeur de l'agrafeuse, il est précisé que ladite bande doit être en appui contre un flanc latéral déterminé du chargeur, avant que l'on ramène le couvercle de sa première à sa deuxième position, dans laquelle le rail passe entre les pattes des agrafes de la bande. En effet, si une bande d'agrafes de largeur de "dos" (distance entre pattes) inférieure à la largeur maximale admissible par l'agrafeuse est en appui sur l'autre flanc du chargeur, et que l'on tente alors de ramener le couvercle porteur du rail de guidage des agrafes à sa deuxième position, dans laquelle il ferme le chargeur, ce rail peut venir buter contre la bande d'agrafes placée dans le chargeur, au lieu de passer librement entre les pattes de ces agrafes. Il n'est alors plus possible de refermer le chargeur et de se servir de l'agrafeuse. We know such staplers, designed for receive staples of different sizes, for example the stapler referenced ROCAFIX MS 10 in the catalogs of the French company Sofragraf Industries. In the instructions that are given for installing a straight strip of staples in the feeder stapler, it is specified that said strip must be in support against a determined lateral flank of the loader, before we bring the cover back from its premiere to its second position, in which the rail passes between the tabs of the tape staples. Indeed, if a band "back" width staples (distance between legs) less than the maximum permissible width by the stapler is resting on the other side of the feeder, and then we try to bring back the carrier cover the staple guide rail in its second position, in which he closes the charger, this rail can come abut against the strip of staples placed in the magazine, instead of passing freely between the legs of these staples. It is then no longer possible to close the feeder and use the stapler.
On connaít de FR-A-2 568 813 une autre agrafeuse conçue pour accepter des agrafes de tailles différentes. Celle-ci comprend un magasin, ou chargeur, allongé comportant deux profilés en U raccordés par un organe central de support servant de rail pour les agrafes. Les deux profilés présentent des largeurs différentes. L'un est de faible largeur, pour enserrer étroitement une des branches, ou pattes, d'une agrafe. L'autre est plus large de manière à pouvoir accueillir l'autre patte de l'agrafe, quelle que soit la largeur de dos de celle-ci, pour autant que cette dernière soit tout de même comprise dans un domaine de largeurs prédéterminé. L'installation d'une bande d'agrafes sur un tel rail exige une certaine attention du fait qu'une partie de la bande doit être enserrée dans un profil en U de faible largeur, à peine supérieur à l'épaisseur du fil constituant les agrafes les plus épaisses que peut recevoir l'agrafeuse.We know from FR-A-2 568 813 another stapler designed to accept staples of different sizes. This includes an elongated magazine or charger comprising two U-shaped profiles connected by a member central support serving as rail for staples. The two profiles have different widths. One is narrow, to enclose tightly one of the branches, or legs, of a staple. The other is wider so that it can accommodate the other staple tab, regardless of the back width of this one, as long as the latter is all even within a range of predetermined widths. The installation of a strip of staples on such a rail requires some attention because part of the strip must be enclosed in a U-shaped profile of narrow width, barely greater than the thickness of the wire making up the thickest staples that can receive the stapler.
La présente invention a pour but de réaliser une agrafeuse du type décrit en préambule de la présente description, qui ne présente aucun des inconvénients mentionnés ci-dessus et qui permette donc la mise en place, sans précautions particulières, d'une pile ou bande d'agrafes dont la largeur de dos peut varier dans un domaine prédéterminé.The object of the present invention is to provide a stapler of the type described in the preamble to this description, which has none of the drawbacks mentioned above and which therefore allows the implementation place, without special precautions, a battery or strip of staples whose back width can vary in a predetermined area.
On atteint ce but de l'invention, ainsi que d'autres qui apparaítront à la lecture de la description qui va suivre, avec une agrafeuse du type décrit en préambule de la présente description, remarquable en ce que le rail est positionné sur le couvercle de chargeur et dimensionné transversalement de manière que, lorsqu'on l'amène à sa deuxième position, il passe librement entre les pattes des agrafes d'une bande de telles agrafes présentant une largeur de dos au moins égale au seuil inférieur dudit domaine de largeurs prédéterminé, que lesdites agrafes soient en appui sur l'un ou l'autre de deux flancs latéraux parallèles du chargeur, et en ce que des moyens de came sont prévus pour déplacer le rail latéralement quand le couvercle passe de sa première à sa deuxième position.This object of the invention is achieved, as well as other which will appear on reading the description which will follow, with a stapler of the type described in the preamble to the present description, remarkable in that the rail is positioned on the charger cover and sized transversely so that when we bring it to its second position, it passes freely between the legs staples of a strip of such staples having a back width at least equal to the lower threshold of said predetermined width range, that said staples are supported on one or the other of two flanks parallel sides of the loader, and in that means cam are provided to move the rail laterally when the cover goes from its first to its second position.
Comme on le verra plus tard, ce déplacement latéral permet d'assurer un guidage étroit de la bande d'agrafes dans le chargeur, quelle que soit la largeur de dos des agrafes de la bande, pour autant que cette largeur soit comprise dans le domaine de largeurs prédéterminé.As we will see later, this lateral displacement allows close guidance of the staple strip in the feeder, regardless of the back width of the tape staples, as long as this width is included in the range of predetermined widths.
D'autres caractéristiques et avantages de la présente invention apparaítront à la lecture de la description qui va suivre et à l'examen du dessin annexé dans lequel :
- la figure 1 est une vue en élévation d'une agrafeuse perfectionnée suivant la présente invention,
- les figures 2 et 3 sont des vues schématiques, en coupe transversale, du chargeur de l'agrafeuse suivant l'invention, prises suivant les traits de coupe II-II et III-III des figures 4 et 5 respectivement, et
- les figures 4 et 5 sont des vues schématiques, en plan, dudit coulisseau, suivant les traits de coupe IV-IV et V-V des figures 2 et 3 respectivement.
- FIG. 1 is an elevation view of an improved stapler according to the present invention,
- FIGS. 2 and 3 are schematic views, in cross section, of the magazine for the stapler according to the invention, taken along the section lines II-II and III-III of FIGS. 4 and 5 respectively, and
- Figures 4 and 5 are schematic plan views of said slide, according to section lines IV-IV and VV of Figures 2 and 3 respectively.
On se réfère à la figure 1 du dessin annexé où il
apparaít que l'agrafeuse suivant l'invention comprend
essentiellement une poignée 1 et un levier 2 que l'on
prend en main pour armer et déclencher, classiquement, un
percuteur 3 propre à détacher l'agrafe de tête d'une
bande ou pile de telles agrafes 4 installée dans un
chargeur 5 de l'agrafeuse. Un organe élastique (non
représenté) pousse la bande d'agrafes dans le sens de la
flèche F, contre une butée définissant la position de
l'agrafe de tête de la bande, au droit du percuteur 3.
Toutes ces dispositions sont bien connues et n'exigent
pas une description plus détaillée. We refer to Figure 1 of the accompanying drawing where it
appears that the stapler according to the invention comprises
essentially a
On remarquera que la poignée 1, le levier 2 et,
d'une manière générale, l'ensemble de l'enveloppe de
l'agrafeuse présentent des formes arrondies à vocation
ornementale seulement.Note that the
On se réfère aux figures 2 à 5 du dessin annexé où
l'on a représenté schématiquement le chargeur 5 de
l'agrafeuse suivant l'invention. Comme cela apparaít aux
figures 2 et 3, celui-ci prend la forme d'un canal
allongé, à section rectangulaire par exemple, fermé par
un couvercle 8. Dans le mode de réalisation représenté, à
titre d'exemple illustratif et non limitatif seulement,
le couvercle 8 prend la forme d'un coulisseau. Le canal
présente un fond 6 1 et des flancs latéraux 6 2 ,6 3 . Ceux-ci
sont creusés de deux rainures 7 1 ,7 2 dans lesquelles glisse
le coulisseau 8 sur lequel est fixé un rail 9 en U,
parallèlement à la grande dimension du coulisseau. Comme
représenté aux figures 2 et 3, les agrafes telles que
l'agrafe 10 i d'une bande 4 de n agrafes (i de 1 à n) sont
montées à cheval dans le chargeur, sur le rail 9.Reference is made to FIGS. 2 to 5 of the appended drawing in which the
L'agrafeuse suivant l'invention est susceptible de
recevoir des agrafes de largeurs de dos différentes et,
éventuellement, d'épaisseurs différentes. On a représenté
aux figures 2 et 3 des agrafes 10 i et 11 i de largeurs l 1
et l 2 et d'épaisseur e 1 et e 2 respectivement, ces agrafes
présentant les largeurs extrêmes d'un domaine prédéterminé
de largeurs acceptables par l'agrafeuse. A titre
d'exemple illustratif et non limitatif, l'agrafeuse peut
ainsi accepter des agrafes de largeurs variant entre
10,57 mm et 11,53 mm, soit une variation de près de 10 %
de la largeur des agrafes.The stapler according to the invention is capable of receiving staples of different back widths and, possibly, of different thicknesses. FIGS. 2 and 3
On remarquera sur les figures 2 et 3 que la largeur
du coulisseau 8 est inférieure à la distance qui sépare
les fonds des rainures 7 1 ,7 2 dans lesquelles glisse ce
coulisseau. Cette disposition permet de faire passer le
coulisseau, et le rail 9 qu'il supporte, de la position
représentée à la figure 2 à celle représentée à la figure
3, et vice versa, pour le but explicité ci-dessus.It will be noted in Figures 2 and 3 that the width of the
Il convient en effet que, quelle que soit la largeur
et l'épaisseur des agrafes placées dans le chargeur 5,
l'agrafe de tête soit parfaitement placée sous le
percuteur 3, dans un plan perpendiculaire à l'axe du
rail. Pour ce faire, il faut qu'au moins sur un côté, par
exemple celui faisant face au flanc 6 2 du chargeur 5, la
bande d'agrafes 4 soit guidée étroitement entre le rail
et ce flanc, comme représenté à la figure 3.It is indeed appropriate that, whatever the width and the thickness of the staples placed in the
Il convient aussi que, le chargeur étant ouvert dans
la position représentée en trait plein à la figure 4, et
une bande d'agrafes 4 déposée au fond du chargeur, on
puisse fermer le chargeur en poussant le coulisseau 8 de
la position représentée à la figure 4 à la position
représentée à la figure 5. Il faut alors, suivant un but
poursuivi par la présente invention, que cette manoeuvre
n'exige aucune précaution particulière de l'opérateur, et
ceci quelle que soit la largeur et/ou la position de la
bande d'agrafes déposée dans le chargeur.It is also advisable that, the magazine being opened in
the position shown in solid lines in FIG. 4, and
a strip of staples 4 deposited at the bottom of the charger,
can close the magazine by pushing the
On atteint ce but de l'invention en faisant passer
le rail 9 d'une position sensiblement centrale dans le
chargeur, représentée à la figure 2, à la position
latérale représentée à la figure 3.This object of the invention is achieved by passing
the
La position centrale illustrée à la figure 2 permet au rail de passer entre les pattes des agrafes, quelle que soit la largeur de celles-ci (comprise entre 1 1 et l 2 ) et quelle que soit le flanc, 6 2 ou 6 3 , du chargeur sur lequel la bande est en appui.The central position illustrated in FIG. 2 allows the rail to pass between the tabs of the staples, whatever their width (between 1 1 and l 2 ) and whatever the side, 6 2 or 6 3 , of the charger on which the strip is supported.
La position latérale illustrée à la figure 3 définit
un canal étroit entre le rail 9 et le flanc 62 du
chargeur, par exemple, de largeur légèrement supérieure à
l'épaisseur de l'agrafe admissible la plus épaisse. Ainsi
l'axe de la bande d'agrafes reste sensiblement parallèle
à celui du rail, ce qui permet de présenter l'agrafe de tête
exactement au droit du percuteur 3, lui-même constitué par
une lame mobile dans un plan perpendiculaire à l'axe du rail.The lateral position illustrated in FIG. 3 defines a narrow channel between the
On a représenté en trait interrompu, à la figure 4,
la position du coulisseau 8 et du rail 9 après que celui-ci
ait commencé à s'engager entre les pattes des agrafes
d'une bande d'agrafes 4 dont l'agrafe de tête est mise en
butée sous le percuteur 3, par la poussée de l'organe
élastique évoqué ci-dessus, symbolisé par la flèche F, et
monté sur le rail 9.There is shown in broken lines, in FIG. 4,
the position of the
Pour que le rail 9 puisse passer sans interférence
entre les pattes des agrafes, lorsqu'on le pousse de la
position de la figure 4 à la position de la figure 5, on
démontre que la largeur R du rail doit être telle que :
Pour que l'agrafe la moins épaisse soit bien guidée
dans l'espace séparant le rail 9 du flanc 6 2 du chargeur,
de largeur égale, à un jeu j près, à l'épaisseur de
l'agrafe la plus épaisse, on contraint, suivant
l'invention, les épaisseurs e 1 et e 2 à satisfaire aux
relations suivantes :
Par ailleurs, lorsque le coulisseau 8 ferme le
chargeur 5, pour assurer un bon guidage de la bande
d'agrafes 4 la plus large, des essais ont montré que la
largeur R du rail 9 pouvait être choisie telle que :
Des relations (1), (3) et (4) ci-dessus, on tire :
Les relations données ci-dessus permettent de
calculer le décalage latéral que doit subir le coulisseau
8 pour amener le rail de la position représentée à la
figure 2 à la position représentée à la figure 3.
Pratiquement ce décalage est obtenu par des moyens de
came prévus aux extrémités des rainures 7 1 ,7 2 , et du
coulisseau 8, comme représenté aux figures 4 et 5. Ces
moyens de came comprennent des cames 12 1 ,12 2 proprement
dites formées aux deux extrémités du coulisseau 8, sur
deux bords opposés de celui-ci, ces cames débordant de
ces bords en présentant la même épaisseur, égale au
décalage calculé. Les cames 12 1 ,12 2 coopèrent avec des
contre-cames 13 1 ,13 2 respectivement, formés au fond des
rainures 7 1 ,7 2 respectivement, à deux extrémités opposées
de celles-ci.The relationships given above make it possible to calculate the lateral offset which the
A leurs autres extrémités opposées, ces rainures
comportent des cames 14 1 ,14 2 , de même hauteur que les
cames et contre-cames précitées, qui coopèrent avec les
bords droits 15 1 ,15 2 en regard du coulisseau 8 pour
maintenir le parallélisme des axes du coulisseau 8 et du
chargeur 5, quand celui-ci est fermé par le coulisseau. Ce
parallélisme assure le positionnement correct des agrafes
sous le percuteur 3, dans un plan perpendiculaire à ses axes.At their other opposite ends, these grooves comprise cams 14 1 , 14 2 , of the same height as the aforementioned cams and counter-cams, which cooperate with the
Pour charger l'agrafeuse avec une bande d'agrafes
telle que définie par ces relations, on ouvre le chargeur
en faisant glisser le coulisseau 8 jusqu'à la position
représentée à la figure 4. On dépose la bande dans le
chargeur de manière que les dos des agrafes reposent
contre le fond de ce chargeur. On referme ensuite le
chargeur en poussant simplement le coulisseau 8 jusqu'à
la position représentée à la figure 5, position dans
laquelle il est retenu par un cliquet (non représenté). Un
bouton de manoeuvre 15 (voir figure 1) permet de débrayer
ce cliquet pour ouvrir le chargeur. Lors du mouvement de
fermeture du chargeur, le rail 8 s'engage à coup sûr
entre les pattes des agrafes, quelle que soit la position
transversale de la bande d'agrafes, et il n'y a alors à
craindre aucun risque de blocage du rail par butée sur la
bande d'agrafes. A la fin du mouvement du coulisseau, les
cames et contre-cames évoquées ci-dessus provoquent
automatiquement le décalage latéral du rail nécessaire au
guidage étroit de la bande d'agrafes.To load the stapler with a strip of staples
as defined by these relationships, we open the loader
by sliding the
Il apparaít maintenant que la présente invention permet bien d'atteindre le but fixé, à savoir assurer une mise en place d'agrafes de largeur variable dans le chargeur d'une agrafeuse, sans précautions particulières et ceci tout en assurant un bon guidage de toutes les bande d'agrafes, de la moins large à la plus large, dans la mesure où les dimensions de ces agrafes sont liées par les relations (2) et (5) ci-dessus.It now appears that the present invention achieves the goal, namely to ensure placement of staples of variable width in the stapler magazine, without special precautions and this while ensuring good guidance of all strip of staples, from the smallest to the widest, in the extent that the dimensions of these staples are linked by relations (2) and (5) above.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté qui n'a été donné qu'à titre d'exemple. C'est ainsi que la présente invention peut être adaptée sans difficulté à un chargeur sur lequel le rail est articulé plutôt que monté à coulissement.Of course, the invention is not limited to the mode described and depicted as an example. This is how this invention can be easily adapted to a charger on which the rail is hinged rather than mounted on sliding.
