- the mechanism of the invention makes it possible to limit the working stroke to a precise measurement, which prevents excessive constraints from being applied to a piece of work.
- the invention makes it possible in particular to produce pliers expansion plug for wall plug engaged in a hole of a wall behind which part of the ankle should be expanded.
- the invention solves the problem posed and allows an implementation cheap work.
- the step-by-step advance mechanism for wall plug expansion clamps and applications similar is characterized in that it has a hollow body associated with a fixed lever and having a hinge pin for a movable lever supporting, by an axis, a pushed pawl by a spring, said pawl comprising a cross member engaged between teeth of an inclined toothing of a rack, delimiting a second toothing with inclined teeth for a cross member supported by a rocker arm to which it applies a compression spring tending to hold said crosspiece between two teeth, said rack being guided inside the body and harnessed to a movable yoke causing expansion of an anchor in cooperation with a fixed screed connected to the body.
- the drawing illustrates a clamp intended to cause expansion an anchor 1 of a well known type which includes a sheath 2 in which is engaged a screw 3 with head 4 which is screwed into a nut 5.
- the pin 1 is engaged in a hole 6 drilled in a wall 7.
- the sheath 2 is deformed as illustrated in 3a in fig. 5, which anchors it behind the wall 7 and causes it to expand against the wall of hole 6.
- clamp which comprises a body 8 preferably of molded material either metallic, or plastic, which delimits an internal housing 9 for the mechanism described below, as well as lateral rebates 10 for the branches 11, 12 of a yoke fixed 13 which is fixed to the body 8 by an axis 14 and a spacer 15.
- the body 8 forms or is attached to a lever 16, said to be fixed, which is provided with a handle 17.
- the axis 14 supports on its side a lever 18, called mobile, constitutes for example by a sheet folded in a U, this lever being provided with a handle 19.
- the handles 17, 19 can be connected by a tilting collar 20.
- the yoke fixed 13 which is preferably metallic, from its branches 11, 12, slides 21, 22, respectively 21a, 22a, which are delimited by folds of the edges lateral.
- the slides 21, 22, 21a, 22a are used for guiding a movable yoke 23 which has, in its front face, a slot 24 coinciding with a slot 25 of the fixed yoke 13.
- the above slots are provided to capture the screw head 4 inside the movable yoke 23, which show fig. 4 and 5.
- the movable yoke guided by the slides 21, 22, 21a, 22a is connected by means of a pin 26 to the end of a rack 27 with upper teeth 28 and teeth lower 29.
- the rack 27 has, moreover, passed in a guide 30 of the body 8.
- the teeth 28, 29 are inclined teeth, the notches 28a, 29a which they have opening towards the front part of the rack, that is to say towards the movable yoke 23.
- a pawl 31 is articulated to the lever 18 on an axis 32 of the latter.
- the pawl 31 has in section the shape of the letter U and supports a cross-member 33 engaged in one of the notches 29a of the toothing 29.
- a pin spring 34 is provided to be wound as shown in the drawing on the axis 32
- the ends of the spring 34 bear respectively against the lever 18 and against the pawl 31, which tends to cause the pawl 31 to pivot in the direction for which the cross-member 33 is applied in one of the notches 29a and to rotate the lever 18 in the direction of the arrow f 1 for which this lever is applied against the end 35a of a rocker arm 35, articulated on the axis 14.
- the rocker arm 35 is constituted by a U-shaped fitting which carries a crosspiece 36 engaged in one of the notches 28a of the toothing 28.
- a compression spring 37 is interposed between a stop 38 of the rack 27 and the rocker arm 35.
- the force of the spring 37 is chosen so that it tends to pivot the rocker arm in the direction of the arrow f 2 so as to always tend to maintain the crosspiece 36 in a notch 38a; this force of the spring 37 is chosen to be higher than that which the pin spring 34 can exert on the movable lever 18 when this lever is applied by its spring 34 against the end 35a of the rocker arm 35 as illustrated in FIG. 4, that is to say when the movable lever 18 occupies a position spaced apart from the fixed lever 16.
- the mechanism described in the above is initially in the position shown in fig. 4, that is to say that the spring 37 exerts a push on the rocker arm 35 to maintain the crossbar 36 in a notch 28a, the rocker arm also bearing against lever 18.
- the pin spring 34 pushes the pawl 31 whose cross member 33 is located itself in a notch 39a, while the movable lever 18 is moved away from the fixed lever 16.
- the position defined above corresponds to that for which the movable yoke 23 is pushed against the fixed yoke 13 by the spring 37.
- the fixed screed as well as the movable screed can thus be engaged behind the screw head 4 of a dowel 1 inserted at gentle friction in a hole 6 in the wall 7.
- the lever 18 can be released and it then pivots in the direction of the arrow f 1 under the action of the pin spring 34 until this lever comes into contact with the end 35a of the rocker arm 35 which acts as a stop, limiting the pivoting of said lever 18.
- Each movement of the rack according to the arrow f 3 has the effect of removing the movable yoke 23 from the fixed yoke 13 and, consequently, causing the flaring of the part of the dowel 1 located behind the wall 7 at the same time that the part of the dowel which is in the hole 6 is inflated and tightened against the wall of this hole.
- This movement has the effect of releasing the cross member 33 from the notch 29a which it occupied and thus freeing the rack 27 by allowing the spring 37 to relax to return the movable yoke 23 to its initial position illustrated in FIG. 4, which allows the extraction of the clamp and its reuse for a new work cycle.

Abstract
Description
La présente invention concerne un nouveau mécanisme qui est destiné essentiellement à être mis en oeuvre dans des pinces et objets analogues, dans lequel il est nécessaire de pouvoir développer des forces importantes sans nécessiter un effort manuel conséquent (voir par exemple GB-A-2 224 230).The present invention relates to a new mechanism which is intended primarily for use in clamps and the like, in which it is necessary to be able develop significant forces without requiring effort consequent manual (see for example GB-A-2 224 230).
En outre, le mécanisme de l'invention fait qu'il est possible de limiter la course de travail à une mesure précise, ce qui enpêche que des contraintes excessives puissent être appliquées à une pièce d'ouvrage.Furthermore, the mechanism of the invention makes it possible to limit the working stroke to a precise measurement, which prevents excessive constraints from being applied to a piece of work.
L'invention permet en particulier de réaliser une pince d'expansion pour cheville murale engagée dans un trou d'une paroi derrière laquelle une partie de la cheville doit être expansée.The invention makes it possible in particular to produce pliers expansion plug for wall plug engaged in a hole of a wall behind which part of the ankle should be expanded.
Il est en effet important que la mesure de l'expansion puisse être contrôlée pour que, d'une part, cette expansion soit suffisante pour maintenir la cheville qui doit aussi être gonflée à l'intérieur du trou par lequel elle est passée et que, d'autre part, l `expansion ne dépasse pas une mesure précise au delà de laquelle la partie expansée deviendrait relativement fragile.It is indeed important that the measure of expansion can be controlled so that, on the one hand, this expansion is sufficient to maintain the ankle which must also be swollen inside the hole she passed through and that, on the other hand, the expansion does not exceed a measure specifies beyond which the expanded part would become relatively fragile.
L'invention résout le problème posé et permet une mise en oeuvre bon marché.The invention solves the problem posed and allows an implementation cheap work.
Conformément à l'invention, le mécanisme d'avance pas à pas pour pince d'expansion de chevilles murales et applications analogues est caractérisé en ce qu'il comporte un corps creux associé à un levier fixe et comportant un axe d'articulation pour un levier mobile supportant, par un axe, un cliquet poussé par un ressort, ledit cliquet comprenant une traverse engagée entre des dents d'une denture inclinée d'une crémaillère, délimitant une seconde denture à dents inclinées pour une traverse que supporte un culbuteur sur lequel s'applique un ressort de compression tendant à maintenir ladite traverse entre deux dents, ladite crémaillère étant guidée à l'intérieur du corps et attelée à une chape mobile provoquant l'expansion d'une cheville en coopération avec une chape fixe reliée au corps.According to the invention, the step-by-step advance mechanism for wall plug expansion clamps and applications similar is characterized in that it has a hollow body associated with a fixed lever and having a hinge pin for a movable lever supporting, by an axis, a pushed pawl by a spring, said pawl comprising a cross member engaged between teeth of an inclined toothing of a rack, delimiting a second toothing with inclined teeth for a cross member supported by a rocker arm to which it applies a compression spring tending to hold said crosspiece between two teeth, said rack being guided inside the body and harnessed to a movable yoke causing expansion of an anchor in cooperation with a fixed screed connected to the body.
Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other features of the invention emerge moreover from the detailed description which follows.
Une forme de réalisation de l'objet de l'invention est
représentée, à titre d'exemple non limitatif, aux dessins
annexés.
Le dessin illustre une pince destinée à provoquer l'expansion
d'une cheville 1 d'un type bien connu qui comporte un
fourreau 2 dans lequel est engagée une vis 3 à tête 4 qui est
vissée dans un écrou 5.The drawing illustrates a clamp intended to cause expansion
an
La cheville 1 est engagée dans un trou 6 foré dans une paroi
7. Lorsque la vis 3 est tirée par sa tête 4, le fourreau 2
est déformé comme illustré en 3a à la fig. 5, ce qui l'ancre
à l'arrière de la paroi 7 et provoque son expansion contre la
paroi du trou 6.The
Pour la mise en place de la cheville 1, décrite ci-dessus, on
met en oeuvre la pince illustrée par le dessin, pince qui
comporte un corps 8 de préférence en matière moulée soit
métallique, soit plastique, qui délimite un logement interne
9 pour le mécanisme décrit dans ce qui suit, ainsi que des
feuillures latérales 10 pour les branches 11, 12 d'une chape
fixe 13 qui est fixée au corps 8 par un axe 14 et une
entretoise 15.For the installation of the
Le corps 8 forme ou est rapporté à un levier 16, dit fixe,
qui est muni d'une poignée 17. L'axe 14 supporte de son côté
un levier 18, dit mobile, constitue par exemple par une tôle
pliée en U, ce levier étant muni d'une poignée 19.The
En position de non utilisation de la pince, les poignées 17,
19 peuvent être reliées par un collier basculant 20. La chape
fixe 13 qui est de préférence métallique forme, à partir de
ses branches 11, 12, des glissières 21, 22, respectivement
21a, 22a, qui sont délimitées par des pliures des bords
latéraux. Les glissières 21, 22, 21a, 22a servent au guidage
d'une chape mobile 23 qui présente, dans sa face avant, une
fente 24 coïncidant avec une fente 25 de la chape fixe 13.
Les fentes ci-dessus sont prévues pour permettre de saisir la
tête de vis 4 à l'intérieur de la chape mobile 23, ce que
montrent bien les fig. 4 et 5. In the position when the pliers are not in use, the
La chape mobile guidée par les glissières 21, 22, 21a, 22a
est reliée au moyen d'un axe 26 à l'extrémité d'une crémaillère
27 présentant une denture supérieure 28 et une denture
inférieure 29. La crémaillère 27 est, par ailleurs, passée
dans un guide 30 du corps 8.The movable yoke guided by the
Comme l'illustre le dessin, les dentures 28, 29 sont des
dentures inclinées, les encoches 28a, 29a qu'elles présentent
ouvrant vers la partie antérieure de la crémaillère
c'est-à-dire vers la chape mobile 23. Un cliquet 31 est articulé
au levier 18 sur un axe 32 de ce dernier. Le cliquet 31
présente en coupe la forme de la lettre U et supporte une
traverse 33 engagée dans l'une des encoches 29a de la denture
29. Un ressort en épingle 34 est prévu pour être enroulé
comme le montre le dessin sur l'axe 32. Les extrémités du
ressort 34 portent respectivement contre le levier 18 et
contre le cliquet 31, ce qui a pour effet de tendre à faire
pivoter le cliquet 31 dans le sens pour lequel la traverse 33
est appliquée dans l'une des encoches 29a et à faire pivoter
le levier 18 dans le sens de la flèche f1 pour lequel ce
levier est appliqué contre l'extrémité 35a d'un culbuteur 35,
articulé sur l'axe 14.As illustrated in the drawing, the
Le culbuteur 35 est constitué par une ferrure en U qui porte
une traverse 36 engagée dans l'une des encoches 28a de la
denture 28.The
Un ressort de compression 37 est interposé entre une butée 38
de la crémaillère 27 et le culbuteur 35. La force du ressort
37 est choisie de façon qu'il tende à faire pivoter le culbuteur
dans le sens de la flèche f2 pour tendre toujours à
maintenir la traverse 36 dans une encoche 38a ; cette force
du ressort 37 est choisie plus élevée que celle que peut
exercer le ressort en épingle 34 sur le levier mobile 18
lorsque ce levier est appliqué par son ressort 34 contre
l'extrémité 35a du culbuteur 35 ainsi que l'illustre la fig.
4, c'est-à-dire lorsque le levier mobile 18 occupe une
position écartée par rapport au levier fixe 16.A
Pour effectuer un cycle de travail, le mécanisme décrit dans
ce qui précède se trouve initialement dans la position illustrée
à la fig. 4, c'est-à-dire que le ressort 37 exerce une
poussée sur le culbuteur 35 pour maintenir la traverse 36
dans une encoche 28a, le culbuteur prenant appui en outre
contre le levier 18. Dans cette position, le ressort en épingle
34 pousse le cliquet 31 dont la traverse 33 se trouve
elle-même dans une encoche 39a, alors que le levier mobile 18
est écarté du levier fixe 16. La position définie ci-dessus
correspond à celle pour laquelle la chape mobile 23
est poussée contre la chape fixe 13 par le ressort 37. La
chape fixe de même que la chape mobile peuvent ainsi être
engagées derrière la tête de vis 4 d'une cheville 1 insérée à
frottement doux dans un trou 6 de la paroi 7.To perform a work cycle, the mechanism described in
the above is initially in the position shown
in fig. 4, that is to say that the
L'opérateur exerce alors une traction sur le levier mobile 18
en rapprochant la poignée 19 qu'il porte de la poignée 17 du
levier fixe 16. Ce mouvement a pour effet que la traverse 33
du cliquet 31 pousse la crémaillère 27 dans le sens de la
flèche f3, ce qui est rendu possible par la forme des encoches
39a. Il s'ensuit que la traverse 36 du culbuteur 35 est
amenée à passer au-dessus d'une ou plusieurs dents inclinées
28 de la crémaillère 27, le ressort 37 ramenant toujours la
traverse 36 dans une encoche 28a au fur et à mesure du déplacement
de la crémaillère 27 suivant la flèche f3. Le mouvement
décrit ci-dessus est illustré par la fig. 5.The operator then exerts traction on the
Dans la position de la fig. 5, le levier 18 peut être libéré
et il pivote alors dans le sens de la flèche f1 sous l'action
du ressort en épingle 34 jusqu'au moment où ce levier vient
en contact avec l'extrémité 35a du culbuteur 35 qui agit
comme une butée, en limitant le pivotement dudit levier 18.In the position of fig. 5, the
On voit par ce qui précède que la traverse 36 du culbuteur 35
est maintenue dans les encoches 28a par l'action exercée par
le ressort 37.It can be seen from the above that the
En exercant à nouveau un effort sur la poignée 19, les mêmes
mouvements que décrits dans ce qui précède se renouvellent,
ce qui provoque un nouveau déplacement de la crémaillère 27
dans le sens de la flèche f3.By again exerting a force on the
Chaque déplacement de la crémaillère suivant la flèche f3 a
pour effet d'écarter la chape mobile 23 de la chape fixe 13
et, par conséquent, de provoquer l'évasement de la partie de
la cheville 1 se trouvant derrière la paroi 7 en même temps
que la partie de la cheville qui se trouve dans le trou 6 est
gonflée et serrée contre la paroi de ce trou.Each movement of the rack according to the arrow f 3 has the effect of removing the
Ce qui précède montre que l'avance suivant la flèche f3 de la
crémaillère s'effectue pas à pas, la mesure de chaque pas
étant déterminée par l'angle de pivotement du levier mobile
18 par rapport au levier fixe 16 et par l'espacement des
dents des dentures 28, 29. La course maximale que peut prendre
la chape mobile 23 est par ailleurs définie par la longueur
sur laquelle s'étendent les dentures 28, 29 de la crémaillère.
On délimite ainsi, à la mesure désirée, l'expansion que
peut prendre la cheville 1 derrière la paroi 7.The above shows that the advance along arrow f 3 of the rack is carried out step by step, the measurement of each step being determined by the pivoting angle of the
Lorsque la cheville 1 est suffisamment expansée, il y a lieu
de libérer la tête de vis 4 pour retirer la pince. L'utilisateur
fait pour cela pivoter le levier mobile 18 dans le sens
de la flèche f1 pour que ce levier vienne réoccuper la position
illustrée à la fig. 4 pour laquelle il bute contre
l'extrémité 35a du culbuteur 35. L'utilisateur exerce alors
une poussée supplémentaire sur le levier mobile 18, ce qui
provoque la levée du culbuteur 35 et le dégagement de la
traverse 36 de l'encoche 28a qu'elle occupait. Par ailleurs,
le culbuteur 35 vient en appui par sa partie postérieure 35b
contre le cliquet 31 en faisant pivoter celui-ci autour de
l'axe 32 suivant la flèche f4. Ce mouvement a pour effet de
dégager la traverse 33 de l'encoche 29a qu'elle occupait et
de libérer ainsi la crémaillère 27 en permettant au ressort
37 de se détendre pour ramener la chape mobile 23 à sa
position initiale illustrée à la fig. 4, ce qui permet
l'extraction de la pince et sa réutilisation pour un nouveau
cycle de travail.When the
L'invention n'est pas limitée à l'exemple de réalisation, représenté et décrit en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre, dans les limites des revendications.The invention is not limited to the embodiment, shown and described in detail because various modifications can be made without departing from its framework, in the limits of the claims.
