The invention concerns a grip system characterised in that each handle (3) has directly mounted or attached, protective elements (5) defining an enclosed space (E) for the user to pass his hands through and wrap them around in gripping position of said handles and to overlap and manoeuvre the control trigger, beneath the grip handle, inside said space (E).

Description

L'invention se rattache au secteur technique des appareils de percussion du type marteau-piqueur, brise-béton, perforateur, fonctionnant avec une source d'énergie quelconque, notamment de l'air comprimé.The invention relates to the technical sector of hammer-type percussion, concrete breaker, perforator, working with any source of energy, especially compressed air.

D'une manière connue, ce type d'appareil présente des poignées de préhension dont l'une au moins est assujettie à une gâchette de commande conformée pour agir sur un dispositif assujetti à la source d'énergie que présente une partie du corps de l'appareil.In a known manner, this type of apparatus has handles of gripping of which at least one is subject to a trigger conformed to act on a device subject to the source of energy that has a part of the body of the device.

Pour tenter de réduire les vibrations importantes résultant du fonctionnement de ces appareils de percussion, on a proposé de suspendre les poignées par rapport au corps de l'appareil, c'est-à-dire de les monter d'une manière oscillante avec capacité de déplacement angulaire dans le même plan que celui défini dans le corps de l'appareil.
   Généralement, les poignées sont montées en débordement latéral du corps de l'appareil, d'une manière opposée, en étant sensiblement alignées.
   La gâchette est portée par l'une des poignées avec laquelle elle oscille donc, tandis que le commutateur à actionner pour la distribution d'énergie nécessaire, est solidaire du corps de l'appareil.In an attempt to reduce the significant vibrations resulting from the operation of these percussion apparatus, it has been proposed to suspend the handles relative to the body of the apparatus, that is to say to mount them in an oscillating manner with the ability to angular displacement in the same plane as that defined in the body of the device.
Generally, the handles are mounted in lateral overflow of the body of the apparatus, in an opposite manner, being substantially aligned.
The trigger is carried by one of the handles with which it oscillates so, while the switch to operate for the required power distribution, is integral with the body of the device.

A partir de cette conception de base, on a proposé de réaliser une commande dont le fonctionnement est indépendant des oscillations des poignées et de leur gâchette de commande. Une solution ressort par exemple de l'enseignement du brevet FR-A-2540774 dans lequel le commutateur possède un poussoir d'ouverture susceptible de coopérer avec un taquet relié à la gâchette. Le taquet est monté oscillant avec la gâchette et la poignée, tandis que le point de contact du poussoir du taquet est sensiblement situé dans l'axe géométrique autour duquel oscille la poignée assujettie à la gâchette de commande.From this basic concept, it has been proposed to carry out a control whose operation is independent of the oscillations of handles and their trigger trigger. One solution stands out example of the teaching of the patent FR-A-2540774 in which the switch has an opening pushbutton capable of cooperating with a cleat connected to the trigger. The cleat is mounted oscillating with the trigger and the handle, while the contact point of the cleat pushbutton is substantially located in the geometric axis around which the handle oscillates subject to the trigger command.

Quelle que soit la forme de réalisation, la gâchette de commande est située au-dessus de la poignée de préhension correspondante, d'où la nécessité de prévoir un moyen de verrouillage afin d'éviter tout déclenchement intempestif compte tenu du positionnement de la gâchette de commande qui n'est pas protégée. Cette obligation d'utiliser un moyen de verrouillage intermédiaire de la gâchette génère une augmentation de poids non négligeable et augmente le nombre de pièces nécessaires au bon fonctionnement.Whatever the embodiment, the trigger is located above the corresponding grip handle, hence the need to provide a means of locking in order to avoid any inadvertent triggering given the trigger position of the command that is not protected. This obligation to use a means of Intermediate trigger lock generates an increase in weight not insignificant and increases the number of parts needed for the correct operation.

L'invention s'est fixée pour but de remédier à ces inconvénients, de manière simple, sûre, efficace et rationnelle.The aim of the invention is to remedy these drawbacks, simple, safe, effective and rational way.

Le problème que se propose de résoudre l'invention est de supprimer cette pièce intermédiaire de verrouillage en évitant tout déclenchement intempestif de la gâchette de commande tout en ayant pour objectif, d'assurer la protection des mains de l'utilisateur. En effet, il apparaít, selon l'état de la technique, que les mains de l'utilisateur ne sont pas protégées, ce qui peut s'avérer important, si l'on considère les conditions difficiles dans lesquelles sont parfois utilisés ces appareils de percussion, les mains de l'utilisateur pouvant être directement exposées avec des risques de blessure.The problem that the invention proposes to solve is to suppress this intermediate piece of locking avoiding any trigger inadvertent trigger trigger while aiming, to ensure the protection of the user's hands. Indeed, it appears, according to state of the art, that the user's hands are not protected, this which can be important, considering the difficult conditions in which are sometimes used these percussion devices, the hands of the user can be directly exposed with risk of injury.

Compte tenu du problème posé à résoudre, il a été conçu et mis au point un système de préhension d'un appareil de percussion du type de ceux comprenant des poignées montées avec capacité d'articulation par rapport au corps de l'appareil, l'une des poignées étant équipée d'une gâchette de commande agissant sur une source d'énergie, Ce type d'appareils ressort de l'enseignement des brevets FR-A-2540774 ou EP-A-0391856.In view of the problem to be solved, it was designed and point a gripping system of a percussion apparatus of the type of those comprising handles mounted with relative hinge capability to the body of the apparatus, one of the handles being equipped with a trigger of control acting on an energy source, this type of apparatus is teaching of patents FR-A-2540774 or EP-A-0391856.

Le problème posé d'assurer à la fois la protection des mains de l'utilisateur et de la gâchette de commande, et d'éviter tout déclenchement intempestif de ladite gâchette, est résolu par les caractéristiques de la revendication 1.The problem of ensuring both the protection of the hands of the user and trigger command, and to avoid any trigger inadvertent of said trigger, is solved by the characteristics of the claim 1.

Pour résoudre le problème posé d'adapter le système de préhension selon l'invention à un appareil de percussion de tout type connu, le corps de chaque élément protecteur constitue un fourreau présentant un chambrage interne de forme et section correspondant à celles de la poignée de préhension.To solve the problem of adapting the gripping system according to the invention to a percussion apparatus of any known type, the body of each protective element constitutes a sleeve having a chambering internal shape and section corresponding to those of the handle of gripping.

Pour résoudre le problème posé d'assurer une parfaite intégration du système de préhension avec le corps de l'appareil et de permettre le débordement de la gâchette de commande à l'intérieur de l'espace défini par les éléments protecteurs, la partie de la forme profilée située du côté du corps de l'appareil fait office de carter apte à enserrer partiellement la section dudit corps, ledit carter présentant une fente pour l'engagement, le débordement et la manoeuvre de la gâchette de commande, sous la poignée de préhension.To solve the problem of ensuring a perfect integration of the grasping system with the body of the device and allow the overflow of the trigger command inside the space defined by the protective elements, the part of the profiled shape on the side of the The body of the apparatus serves as a housing adapted to partially grip the section of said body, said housing having a slot for engagement, overflow and maneuvering the trigger switch, under the handle grasping.

Le système de préhension selon l'invention trouve une application particulièrement avantageuse dans le cas où l'appareil comprend deux poignées opposées montées articulées de part et d'autre d'une tête que présente la partie supérieure du corps de l'appareil.
   Compte tenu des caractéristiques de l'invention et du montage des éléments protecteurs par rapport aux poignées que présente d'origine l'appareil de percussion, la tête est coiffée par un élément apte à assurer le raccordement visuel entre les deux parties faisant office de carter.
   A partir de cette conception :

  • soit l'élément de liaison est indépendant et rapporté pour être fixé au niveau de la tête ;
  • soit l'élément de liaison est rendu solidaire avec capacité d'articulation des éléments de protection, notamment de la partie faisant office de carter, de manière à constituer un ensemble unitaire.
The gripping system according to the invention finds a particularly advantageous application in the case where the apparatus comprises two opposite handles mounted articulated on either side of a head that has the upper part of the body of the apparatus.
Given the characteristics of the invention and the mounting of the protective elements with respect to the handles that the original percussion device, the head is capped by an element capable of ensuring the visual connection between the two parts acting as a housing .
From this design:
  • either the connecting element is independent and reported to be fixed at the level of the head;
  • either the connecting element is made integral with articulating ability of the protective elements, including the part acting as a housing, so as to constitute a unitary assembly.

L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés dans lesquels :

  • la figure 1 est une vue en perspective d'un exemple d'appareil de percussion équipé du système de préhension selon l'invention ;
  • la figure 2 est une vue en perspective de l'un des éléments protecteurs du système ;
  • la figure 3 est une vue en coupe longitudinale montrant le montage du système préhension par rapport aux poignées ;
  • la figure 4 est une vue en coupe transversale considérée selon la ligne 4-4 de la figure 3.
The invention is described below in more detail with reference to the figures of the accompanying drawings, in which:
  • Figure 1 is a perspective view of an exemplary percussion apparatus equipped with the gripping system according to the invention;
  • Figure 2 is a perspective view of one of the protective elements of the system;
  • Figure 3 is a longitudinal sectional view showing the mounting of the gripping system relative to the handles;
  • FIG. 4 is a cross-sectional view taken along the line 4-4 of FIG. 3.

On a illustré, figure 1, un exemple nullement limitatif d'un appareil de vibration sous forme d'un marteau brise-béton. Cet appareil comprend un corps (1) surmonté par une tête rigide (2). La tête (2) est équipée, en débordement latéral, de deux poignées opposées (3) montées avec capacité d'oscillation. En outre, la tête reçoit une gâchette de commande (4) apte à déclencher à volonté une source d'énergie à commande ou non d'un outil de percussion (non représenté). Ces dispositions sont parfaitement connues pour un homme du métier et ne font pas partie de l'objet spécifique de l'invention.FIG. 1 illustrates a non-limiting example of a device of vibration in the form of a breaker hammer. This device includes a body (1) surmounted by a rigid head (2). The head (2) is equipped, in lateral overflow, two opposite handles (3) mounted with capacity oscillation. In addition, the head receives a control trigger (4) adapted to trigger at will a power source controlled or not a tool of percussion (not shown). These provisions are perfectly known for a person skilled in the art and are not part of the specific object of the invention.

Selon une caractéristique à la base de l'invention, chaque poignée (3) présente, directement ou d'une manière rapportée, des éléments protecteurs (5) délimitant un espace fermé (E). Cet espace fermé (E) a pour fonction, d'une part, de permettre le passage et l'enveloppement des mains de l'utilisateur en position de préhension des poignées et, d'autre part, permettre le débordement de la gâchette de commande (4).According to a characteristic at the base of the invention, each handle (3) presents, directly or in a reported way, protective elements (5) delimiting a closed space (E). This closed space (E) has the function, on the one hand, to allow the passage and wrapping of the hands of the user in the gripping position of the handles and, on the other hand, the overflow of the control trigger (4).

Comme le montre la figure 2, l'élément protecteur (5) comprend un corps (5a) apte à envelopper, en totalité ou en partie, la section de la poignée correspondante (3). Avantageusement, le corps (5a) constitue un fourreau présentant un chambrage interne (5a1) de forme et section complémentaires de celles de la poignée de préhension (3). Ces dispositions permettent une indexation angulaire du corps (5a) et par conséquent de l'ensemble de l'élément protecteur (5) par rapport à la poignée (3). Une vis (6) ou autre, engagée au niveau du corps (5a) et de la poignée (3), assure le blocage en translation de l'ensemble de l'élément protecteur (5) par rapport à ladite poignée (3).As shown in FIG. 2, the protective element (5) comprises a body (5a) capable of wrapping, in whole or in part, the section of the corresponding handle (3). Advantageously, the body (5a) constitutes a sheath having an internal chamber (5a1) of shape and section complementary to those of the handle (3). These provisions allow angular indexation of the body (5a) and consequently the entire protective element (5) with respect to the handle (3). A screw (6) or other, engaged at the body (5a) and the handle (3), ensures the locking in translation of the entire protective element (5) with respect to said handle (3).

Les extrémités du corps (5a) sont réunies par une forme profilée (5b) délimitant l'espace (E) en faisant office de sous-garde. La partie (5b1) de la forme profilée (5b) située du côté du corps de l'appareil, notamment de la tête (2), fait office de carter apte à enserrer partiellement la section de la tête (2). Le chambrage (5a1) du corps (5a) débouche au niveau de cette partie (5b1) pour permettre l'introduction des poignées (3).The ends of the body (5a) are joined by a shaped shape (5b) delimiting the space (E) as an under guard. Part (5b1) of the shaped form (5b) located on the side of the body of the apparatus, in particular the head (2) serves as a housing adapted to partially enclose the section of the head (2). The chambering (5a1) of the body (5a) opens at this part (5b1) to allow the introduction of the handles (3).

En outre, le carter (5b1) présente une fente (5c) pour l'engagement, le débordement et la manoeuvre de la gâchette de commande (4). La fente (5c) est établie sous le chambrage (5a1) de manière à ce que la gâchette (3) soit située sous la poignée de préhension, c'est-à-dire sous le corps (5a), à l'intérieur de l'espace de protection (E).In addition, the housing (5b1) has a slot (5c) for engagement, overflow and operation of the control trigger (4). The slot (5c) is established under the recess (5a1) so that the trigger (3) is located under the handle, that is to say under the body (5a), to inside the protection space (E).

L'ensemble de l'élément protecteur (5) tel que défini est avantageusement réalisé par injection d'une matière plastique. A noter qu'à l'opposé de la partie (5b1) de la forme profilée (5b) faisant office de sous-garde, la partie (5b2), au niveau du corps (5a), est pleine. A noter également que les formes de la partie profilée (5b) faisant office de sous-garde sont judicieusement déterminées afin de ne pas altérer l'oscillation des poignées de préhension. C'est le cas notamment au niveau du raccordement de la partie inférieure de la partie (5b3) de la sous-garde avec la partie (5b1) faisant office de carter.The entire protective element (5) as defined is advantageously produced by injection of a plastic material. Note that the opposite of the part (5b1) of the profiled form (5b) acting as an under guard, the portion (5b2) at the body (5a) is full. Also note that the shapes of the profiled part (5b) serving as the sub-guard are carefully determined so as not to alter the oscillation of the handles grasping. This is particularly the case with the connection of the lower part of the part (5b3) of the sub-guard with the part (5b1) acting as a crankcase.

Le système de préhension tel que défini selon les caractéristiques de l'invention, peut également être complété par un élément de liaison (7) profilé en section pour coiffer la partie supérieure de la tête (2) et assurer un raccordement visuel entre deux éléments protecteurs (5) notamment entre les deux parties (5b1) faisant office de carter. Cet élément de liaison (7) peut être indépendant et rapporté pour être fixé par tout moyen connu et approprié au niveau de la tête (2).The gripping system as defined according to the characteristics of the invention can also be completed by a connecting element (7) sectional section for covering the upper part of the head (2) and ensuring a visual connection between two protective elements (5) in particular between the two parts (5b1) acting as crankcase. This connecting element (7) can be independent and reported to be fixed by any known means and suitable for the head (2).

Sans pour cela sortir du cadre de l'invention, on n'exclut pas une forme de réalisation selon laquelle l'élément de liaison (7) est rendu solidaire, avec capacité d'articulation, de chacun des éléments de protection (5) notamment au niveau de la partie faisant office de carter (5b1), de manière à constituer un ensemble unitaire. La liaison articulée entre l'élément de liaison (7) et chacun des éléments de protection (5) peut être obtenu par tout moyen connu au moment du moulage de l'ensemble du système de préhension. Ces dispositions permettent de conserver le montage oscillant des poignées.Without departing from the scope of the invention, one does not exclude a embodiment according to which the connecting element (7) is rendered solidary, with articulation capacity, of each of the protective elements (5) in particular at the crankcase portion (5b1), to constitute a unitary whole. The articulated connection between the connecting element (7) and each of the protection elements (5) can be obtained by any means known at the time of molding the whole of the gripping system. These provisions make it possible to preserve the assembly swinging handles.

Compte tenu de ces dispositions, il apparaít que la gâchette de commande peut être montée sous l'une des poignées de préhension évitant ainsi l'utilisation d'une pièce intermédiaire de verrouillage. La gâchette est parfaitement protégée dans l'espace défini. Il en est de même en ce qui concerne les mains de l'utilisateur.In view of these provisions, it appears that the trigger of control can be mounted under one of the gripping handles avoiding thus the use of an intermediate locking part. The trigger is perfectly protected in the defined space. It is the same with regards the hands of the user.

Les avantages ressortent bien de la description.The advantages are apparent from the description.
