Description

Les outils, ustensiles, outillages ou instruments manuels disposent d'un manche en bois qui doit être assemblé à l'ensemble de l'outil, par exemple, des marteaux, des haches, des houes, etc.Tools, utensils, tools, or hand tools have a wooden handle that must be assembled to the whole tool, for example, hammers, axes, hoes, etc.

Cet assemblage se détériore peu à peu à la suite de son utilisation et aux coups répétés constants, qui donnent lieu à des usures et des jeux préjudiciables.This assembly deteriorates little by little as a result of its use and the repeated repeated blows, which give rise to wear and games prejudicial.

Ce Brevet résout ce problème en permettant un assemblage de réglage et/ou de précision entre le manche et l'outil, qui est conservé sans jeux en dépit du temps, de l'utilisation et des coups, et il est capable d'être régulé dans son réglage-serrage, en obtenant une sécurité maximale qui empêche le dérèglement du réglage et la sortie du manche hors de l'outil.This patent solves this problem by allowing an assembly of adjustment and / or precision between the handle and the tool, which is kept without games despite the time, use and blows, and is able to be regulated in its adjustment-tightening, obtaining a maximum safety which prevents the disturbance of the adjustment and the exit of the handle out of the tool.

Avec l'assemblage qui fait l'objet de l'invention, on prolonge la durée de vie de l'outil et on en maintient les prestations dans le temps comme au premier jour d'utilisation.With the assembly that is the subject of the invention, it extends the life of the tool and maintains the benefits in time as the first day of use.

L'objet de la présente invention particularise cet assemblage entre le manche et l'outil dans lequel :

  1. a) l'outil dispose d'un orifice où vient s'encastrer la tête du manche, la surface extrême de cette tête de manche demeurant libre,
  2. b) disposant d'une vis de fixation, avec autobloquant incorporé à la propre vis, dont le corps s'assemble par vissage, indirectement à la tête du manche, et qui comprend une tête qui vient buter indirectement sur l'outil en employant une rondelle, si bien que la tête du manche peut se déplacer longitudinalement en faisant fonction d'écrou par rapport à la vis de fixation.
The object of the present invention particularizes this assembly between the handle and the tool in which:
  1. a) the tool has an orifice where the head of the handle is embedded, the extreme surface of this sleeve head remaining free,
  2. b) having a fixing screw, with self-locking incorporated in the own screw, whose body assembles by screwing, indirectly to the head of the handle, and which includes a head that comes indirectly abut the tool by using a washer, so that the head of the handle can move longitudinally acting as a nut relative to the fixing screw.

Selon une réalisation préférée, l'orifice de l'outil est borgne au moyen d'une paroi frontale, où s'encastre la tête du manche, la surface extrême de cette tête de manche demeurant libre à l'intérieur de cet orifice borgne.According to a preferred embodiment, the orifice of the tool is blind by means of a front wall, which fits the head of the handle, the end surface of this sleeve head remaining free inside this blind hole.

Selon une autre réalisation préférée :

  1. a) l'orifice de l'outil est passant, se composant d'une zone d'entrée et d'une zone de sortie, la surface de la zone de sortie étant, au moins, convergente vers l'intérieur de l'orifice ;
  2. b) le manche dispose d'une tête de manche avec une zone entrante et une zone sortante, la surface extérieure de la zone entrante étant conjuguée avec la zone correspondante de l'orifice de l'outil où elle est encastrée, la surface extrême de cette tête de manche étant libre et présentant un orifice intérieur à la sortie duquel, dans la zone sortante, on dispose une cale qui, en exerçant une pression dans la zone sortante, fait qu'elle soit conjuguée avec la zone correspondante de l'orifice de l'outil où elle demeure encastrée.
According to another preferred embodiment:
  1. a) the orifice of the tool is passing, consisting of an entrance zone and an exit zone, the surface of the exit zone being at least convergent towards the interior of the orifice; ;
  2. b) the handle has a sleeve head with an inbound area and an outgoing area, the outside surface of the entering area being conjugated with the corresponding area of the tool hole where it is embedded, the end surface of this sleeve head being free and having an internal orifice at the exit of which, in the outgoing zone, there is a wedge which, by exerting a pressure in the outgoing zone, makes it conjugate with the corresponding zone of the orifice of the tool where it remains embedded.

Pour mieux comprendre l'objet de la présente invention, on représente sur les plans une forme préférentielle de réalisation pratique, susceptible de changements accessoires qui n'en dénaturent pas le fondement.To better understand the object of the present invention, there is shown on the plans a preferred form of practical realization, susceptible of incidental changes that do not distort the foundation.

La figure 1 est une section longitudinale d'une réalisation pratique de l'objet de l'invention.The figure 1 is a longitudinal section of a practical embodiment of the subject of the invention.

La figure 2 est une section longitudinale d'une réalisation alternative de l'objet de l'invention.The figure 2 is a longitudinal section of an alternative embodiment of the subject of the invention.

La figure 3 est une section longitudinale d'une réalisation pratique alternative de l'objet de l'invention, conformément à la figure 2, avec une rondelle de butée (19).The figure 3 is a longitudinal section of an alternative practical embodiment of the subject of the invention, in accordance with the figure 2 with a thrust washer (19).

On décrit ci-dessous un exemple de réalisation pratique, non limitative, de la présente invention.An exemplary practical, non-limiting embodiment of the present invention is described below.

Conformément à la figure 1 :

  • L'outil (2) joue le rôle de pièce femelle et, pour cela, dispose d'un orifice (11) où s'encastre la tête du manche (1) qui fait fonction de pièce mâle.
  • La surface de l'orifice (11) et la surface extérieure de la tête du manche (1) sont conjuguées, parfaitement ajustées entre elles, par exemple, parce que toutes les deux ont reçu un usinage de précision. Le blocage entre les deux surfaces est parfait.
  • La surface de l'orifice (11) est convergente, autrement dit, la surface de sa section diminue peu à peu le long de l'orifice, cette section présentant n'importe quelle forme, allant de la circulaire elliptique à la polygonale.
In accordance with the figure 1 :
  • The tool (2) acts as a female part and, for this, has an orifice (11) where the head of the handle (1) which functions as a male part fits.
  • The surface of the orifice (11) and the outer surface of the head of the handle (1) are conjugate, perfectly fitted together, for example, because both have been precision machined. The blockage between the two surfaces is perfect.
  • The surface of the orifice (11) is convergent, that is, the surface of its section decreases gradually along the orifice, this section having any shape, ranging from the elliptical circular to the polygonal.

L'orifice (11) est borgne, obturé au moyen d'une paroi frontale (20) qui forme un tout unique avec l'outil (2) lui-même.The orifice (11) is blind, closed by means of a front wall (20) which forms a single whole with the tool (2) itself.

Cette paroi frontale (20) comporte un petit orifice (21) traversé par la vis de fixation (7) qui se visse indirectement à la tête du manche (1) au moyen d'un troisième élément (3), qui est fixé à cette tête du manche (1).This front wall (20) has a small orifice (21) through which the fastening screw (7) passes, which is screwed indirectly to the head of the handle (1) by means of a third element (3), which is fixed to this head of the handle (1).

En particulier, et conformément à la réalisation représentée, ledit orifice (21) où se loge la vis (7) conforme un fraisage (22) où l'on dispose une rondelle (6), si bien que la tête (9) de la vis de fixation (7) vient buter indirectement sur l'outil (2) et, au moment du vissage, la tête du manche (1) peut se déplacer longitudinalement en faisant fonction d'écrou par rapport à la vis de fixation (7).In particular, and in accordance with the embodiment shown, said orifice (21) accommodating the screw (7) conforms to a milling (22) where a washer (6) is arranged, so that the head (9) of the fixing screw (7) abuts indirectly on the tool (2) and, at the time of screwing, the head of the handle (1) can move longitudinally by acting as a nut relative to the fixing screw (7) .

L'orifice borgne (11), la tête du manche (1), le troisième élément (3) et la vis (7) qui les unit sont coaxiaux.The blind hole (11), the head of the handle (1), the third element (3) and the screw (7) which unites them are coaxial.

Additionnellement, la tête du manche (1) est ajustée avec un serrage dans, au moins, la zone de l'embouchure (a1) de l'orifice borgne (11) du manche (1) -zone (a1) sur la figure 1-.Additionally, the head of the handle (1) is adjusted with a tightening in at least the region of the mouth (a 1 ) of the blind hole (11) of the handle (1) -zone (a 1 ) on the figure 1 -.

Conformément à la figure 2 :

  • l'outil (2) joue le rôle de pièce femelle et, pour cela, dispose d'un orifice passant (11') où vient s'encastrer la tête du manche (1) qui fait fonction de pièce mâle.
  • la surface de l'orifice passant (11') et la surface extérieure de la tête du manche (1) sont conjuguées, parfaitement ajustées entre elles, par exemple, parce que toutes les deux ont reçu un usinage de précision. Le blocage entre les deux surfaces est parfait.
In accordance with the figure 2 :
  • the tool (2) acts as a female part and, for this, has a through hole (11 ') which is embedded in the head of the handle (1) which acts as a male part.
  • the surface of the passing orifice (11 ') and the outer surface of the head of the handle (1) are conjugate, perfectly fitted together, for example, because both have been precision machined. The blockage between the two surfaces is perfect.

L'orifice passant (11') présente une zone d'entrée (111) et une zone de sortie (112) qui ont des surfaces convergentes vers le centre de l'orifice passant (11'), par exemple deux troncs de cône, troncopyramidaux, etc., et ayant une quelconque section, par exemple, circulaire, elliptique ou polygonale.The passing orifice (11 ') has an inlet zone (11 1 ) and an outlet zone (11 2 ) which have convergent surfaces towards the center of the passing orifice (11'), for example two trunks of cone, truncopyramidal, etc., and having any section, for example, circular, elliptical or polygonal.

La tête du manche (1) présente une zone entrante (Z1) et une zone sortante (Z2) dont les surfaces extérieures sont conjuguées avec celles que présentent les zones correspondantes dans l'orifice passant (11') une fois que la cale (5) a agi comme on l'explique ci-dessous.The head of the handle (1) has an incoming zone (Z 1 ) and an outgoing zone (Z 2 ) whose outer surfaces are conjugate with those that present the corresponding zones in the passing orifice (11 ') once the wedge (5) acted as explained below.

La tête du manche (1) demeure encastrée dans l'orifice passant (11').The head of the handle (1) remains embedded in the through hole (11 ').

Un orifice intérieur (40) est pratiqué dans la tête du manche (1) à la sortie duquel (31) on dispose une cale (5).An inner hole (40) is formed in the head of the handle (1) at the exit of which (31) there is a shim (5).

De préférence, la zone sortante (Z2) présente une rainure ou une zone d'expansion, qui en permet la pénétration/introduction par la zone de plus petit rayon (Z3) de l'orifice passant, la zone sortante (Z2) se positionnant dans la zone de sortie (112) de l'orifice passant (11') et s'ajustant à cette surface de sortie (112) au moyen de la cale (5), par exemple, tronconique. La zone sortante (Z2) est déformable, expansible.Preferably, the outgoing zone (Z 2 ) has a groove or an expansion zone, which allows the penetration / introduction by the zone of smaller radius (Z 3 ) of the passing orifice, the outgoing zone (Z 2 ) is positioned in the outlet area (11 2 ) of the passing orifice (11 ') and fitting to this outlet surface (11 2 ) by means of the wedge (5), for example, frustoconical. The outgoing zone (Z 2 ) is deformable, expandable.

On dispose d'une vis de fixation (7) pour assembler la tête du manche (1) avec l'outil (2) en disposant pour cela d'un troisième élément (3) qui se fixe à la tête du manche (1), par exemple, par vissage (13) d'un bossage pointu (12) qui pénètre profondément dans la tête du manche (1), ou par tout autre moyen conventionnel.A fastening screw (7) is available to assemble the head of the handle (1) with the tool (2) by providing for this a third element (3) which is fixed to the head of the handle (1) for example, by screwing (13) a pointed boss (12) which penetrates deeply into the head of the handle (1), or by any other conventional means.

La section du corps (14) du troisième élément (3) peut être n'importe laquelle.The body section (14) of the third element (3) can be any one.

En particulier et conformément à la réalisation représentée sur les figures 2 et 3, ladite vis de fixation (7) conforme un fraisage (22) où l'on dispose une rondelle-ressort (6), si bien que la tête (9) de la vis de fixation (7) vient buter indirectement sur l'outil (2) au moyen de la cale (5) et, en vissant, la tête du manche (1) peut se déplacer longitudinalement en faisant fonction d'écrou par rapport à la vis de fixation (7).In particular and in accordance with the embodiment shown on the figures 2 and 3 said fixing screw (7) conforms to a milling (22) where a spring washer (6) is provided, so that the head (9) of the fastening screw (7) abuts indirectly on the tool (2) by means of the shim (5) and, by screwing, the head of the handle (1) can move longitudinally acting as a nut with respect to the fixing screw (7).

L'orifice passant (11'), la tête du manche (1), le troisième élément (3) et la vis (7) qui les unit sont coaxiaux.The passing orifice (11 '), the head of the handle (1), the third element (3) and the screw (7) which unites them are coaxial.

La vis de fixation (7) peut être plus ou moins serrée et on peut corriger les jeux qui apparaissent entre la tête du manche (1) et l'outil (2) dans l'orifice passant (11'), donnant lieu à un assemblage ajusté dans toute la section de frottement entre l'outil (2), la tête du manche (1) et la cale (5).The fixing screw (7) can be more or less tight and it is possible to correct the clearances that appear between the head of the handle (1) and the tool (2) in the through hole (11 '), giving rise to a assembly adjusted throughout the friction section between the tool (2), the head of the handle (1) and the wedge (5).

Dans la réalisation de la figure 3, on a disposé une rondelle de butée (19) fixée à l'outil (2), une rondelle-ressort (6) entre la tête (9) de la vis de rotation (7) et la rondelle de butée (19), ce qui donne lieu à une force de traction, par exemple, constante entre l'outil (2) et la zone entrante (Z1) de la tête du manche (1) et à de seconds moyens mécaniques de traction (10) entre la rondelle de butée (19) et la cale (5), ce qui donne lieu à une force de traction, par exemple, constante entre l'outil (2) et la zone sortante (Z2) de la tête du manche (1) au moyen de la cale (5), autrement dit, des efforts d'ajustement entre les deux zones tronconiques (Z1), (Z2).In the realization of the figure 3 an abutment washer (19) fixed to the tool (2) is provided with a spring washer (6) between the head (9) of the rotation screw (7) and the thrust washer (19), which gives rise to a traction force, for example, constant between the tool (2) and the incoming zone (Z 1 ) of the head of the handle (1) and to second mechanical means of traction (10) between the thrust washer (19) and the shim (5), which gives rise to a traction force, for example, constant between the tool (2) and the outgoing zone (Z 2 ) of the head of the handle (1) by means of the wedge (5), in other words, adjustment forces between the two frustoconical zones (Z 1 ), (Z 2 ).

Entre l'outil (2) et la rondelle de butée (19), on dispose une goupille anti-rotation (11).Between the tool (2) and the thrust washer (19) is provided an anti-rotation pin (11).

Dans les deux réalisations :

  • La vis de fixation (7) comporte un autobloquant (4) incorporé dans la propre vis. Plus particulièrement, l'autobloquant (4) est appliqué directement sur le corps (16) de la vis (7) si bien que, au moment du coup, les vibrations ne peuvent pas dévissert la vis (7).
In both achievements:
  • The fixing screw (7) comprises a self-locking device (4) incorporated in the own screw. More particularly, the self-blocking (4) is applied directly to the body (16) of the screw (7) so that, at the time of the blow, the vibrations can not unscrew the screw (7).

L'assemblage entre le troisième élément (3) mentionné et la tête du manche (1) s'effectue d'une double façon :

  1. a) en conformant à l'extrémité de l'élément (3) un bossage (12) vissé extérieurement (13);
  2. b) en disposant radialement une goupille (8) qui assure la fonction anti-rotation de cet élément (3) par rapport à la tête du manche (1) et la fonction de butée axiale contre cette tête du manche (1) en empêchant ainsi le désassemblage de ce troisième élément (3) et de la tête du manche (1).
The connection between the third element (3) mentioned and the head of the handle (1) is done in two ways:
  1. a) conforming to the end of the element (3) a boss (12) screwed externally (13);
  2. b) radially arranging a pin (8) which provides the anti-rotation function of this element (3) relative to the head of the handle (1) and the axial stop function against this head of the handle (1) thereby preventing disassembling this third element (3) and the head of the handle (1).
