Description

SYSTEME DE PREHENSION D'UN APPAREIL DE PRECUSSIONGRIPPING SYSTEM OF A PRECUSSION APPARATUS
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 percussion devices of the jackhammer, concrete breaker, perforator type, operating with any energy source, in particular 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 device has grips, at least one of which is subject to a control trigger configured to act on a device subject to the source of energy that a part of the body of the 'apparatus.
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.In an attempt to reduce the significant vibrations resulting from the operation of these percussion devices, it has been proposed to suspend the handles relative to the body of the device, 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.
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.Generally, the handles are mounted in lateral overflow from the body of the device, in an opposite manner, being substantially aligned. The trigger is carried by one of the handles with which it therefore oscillates, while the switch to be actuated for the distribution of necessary energy, is secured to 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 83.02876 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 design, it has been proposed to produce a control whose operation is independent of the oscillations of the handles and of their control trigger. A solution emerges for example from the teaching of patent FR 83.02876 in which the switch has an opening pusher capable of cooperating with a stopper connected to the trigger. The cleat is mounted oscillating with the trigger and the handle, while the point of contact of the pusher of the cleat is substantially situated in the geometric axis around which the handle subject to the control trigger oscillates.
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 control trigger is located above the corresponding grip handle, hence the need to provide a locking means in order to avoid any untimely triggering given the positioning of the trigger. command that is not protected. This obligation to use an intermediate trigger locking means generates a significant increase in weight and increases the number of parts necessary for proper operation.
L'invention s'est fixée pour but de remédier à ces inconvénients, de manière simple, sûre, efficace et rationnelle.The object of the invention is to remedy these drawbacks in a simple, safe, effective and rational manner.
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 apparaît, 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. Compte tenu du problème posé à résoudre, il a été conçu et mis au point un système de préhension d'un appareil de percussion notamment 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, remarquable en ce que chaque poignée présente, directement ou d'une manière rapportée, des éléments protecteurs délimitant un espace fermé pour, d'une part, le passage et l'enveloppement des mains de l'utilisateur en position de préhension desdites poignées et, d'autre part, le débordement et la manœuvre de la gâchette de commande, sous la poignée de préhension, à l'intérieur dudit espace.The problem which the invention proposes to solve is to eliminate this intermediate locking piece while avoiding any untimely triggering of the control trigger while having the objective of ensuring the protection of the hands of the user. Indeed, it appears, according to the state of the art, that the user's hands are not protected, which can be important, if we consider the difficult conditions in which these devices are sometimes used. impact, the user's hands may be directly exposed with risk of injury. Given the problem to be solved, it has been designed and developed a gripping system of a percussion device in particular comprising handles mounted with capacity for articulation relative to the body of the device, one of the handles being equipped with a control trigger acting on an energy source, remarkable in that each handle has, directly or in a reported manner, protective elements delimiting a closed space for, on the one hand, the passage and the 'wrapping of the user's hands in the gripping position of said handles and, on the other hand, the overflow and the operation of the control trigger, under the gripping handle, inside said space.
Le problème posé d'assurer à la fois la protection des mains de l'utilisateur et de la gâchette de commande, est résolu en ce que chaque élément protecteur comprend un corps apte à envelopper, en totalité ou en partie, la section de la poignée correspondante, les extrémités dudit corps étant réunies par une forme profilée délimitant l'espace en faisant office de sous-garde.The problem posed of ensuring both the protection of the user's hands and of the control trigger is solved in that each protective element comprises a body capable of enveloping, in whole or in part, the section of the handle. corresponding, the ends of said body being joined by a profiled shape delimiting the space by acting as a sub-guard.
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 posed of adapting the gripping system according to the invention to a percussion device of any known type, the body of each protective element constitutes a sheath having an internal recess of shape and section corresponding to those of the handle. 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 resolve the problem posed, ensure perfect integration of the gripping system with the body of the device and allow the overflow of the control trigger inside the space defined by the protective elements, the part of the profiled shape located on the side of the body of the device acts as a casing capable of partially enclosing the section of said body, said casing having a slot for the engagement, the overflow and the operation of the control trigger, under the grip handle.
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.The gripping system according to the invention finds a particularly advantageous application in the case where the device comprises two opposite handles mounted articulated on either side of a head which has the upper part of the body of the device.
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 :Taking into account the characteristics of the invention and the mounting of the protective elements with respect to the handles which the percussion device has from the outset, the head is capped by an element capable of ensuring the visual connection between the two parts serving as a housing. . From this conception:
• soit l'élément de liaison est indépendant - et rapporté pour être fixé au niveau de la tête ;• either the connecting element is independent - and attached to be fixed at head level;
• 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.• either the connecting element is made integral with the ability to articulate the protective elements, in particular of the part serving as a casing, so as to constitute a unitary assembly.

- 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.- Figure 3 is a longitudinal sectional view showing the mounting of the gripping system relative to the handles; - Figure 4 is a cross-sectional view taken along line 4-4 of Figure 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.Illustrated in Figure 1, a non-limiting example of a vibration device in the form of a concrete breaker hammer. This device comprises a body (1) surmounted by a rigid head (2). The head (2) is equipped, in lateral overflow, with two opposite handles (3) mounted with oscillation capacity. In addition, the head receives a control trigger (4) capable of triggering an energy source at will with or without the command of a percussion tool (not shown). These provisions are perfectly known to a person skilled in the art and do not form 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) has, directly or in an attached manner, protective elements (5) delimiting a closed space (E). This closed space (E) has the function, on the one hand, of allowing the passage and envelopment of the hands of the user in the gripping position of the handles and, on the other hand, of allowing the control trigger to overflow (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 (5 a) constitue un fourreau présentant un chambrage interne (5al) 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 Figure 2, the protective element (5) comprises a body (5a) capable of enveloping, in whole or in part, the section of the corresponding handle (3). Advantageously, the body (5 a) constitutes a sheath having an internal recess (5al) of shape and section complementary to those of the grip handle (3). These provisions allow angular indexing of the body (5a) and therefore of the entire protective element (5) relative to the handle (3). A screw (6) or the like, engaged at the level of the body (5a) and of the handle (3), ensures the locking in translation of the assembly of the protective element (5) relative 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 (5b 1) 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 (5al) du corps (5a) débouche au niveau de cette partie (5bl) pour permettre l'introduction des poignées.(3). ' The ends of the body (5a) are joined by a profiled shape (5b) delimiting the space (E) by acting as a sub-guard. The part (5b 1) of the profiled shape (5b) located on the side of the body of the device, in particular of the head (2), acts as a casing capable of partially enclosing the section of the head (2). The recess (5al) of the body (5a) opens at this part (5bl) to allow the introduction of the handles. (3).
En outre, le carter (5bl) 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 (5al) de manière à ce que la gâchette (3) soit située sous la poignée de préhension, c'est-à-dire sous le corps (5 a), à l'intérieur de l'espace de protection (E).In addition, the housing (5bl) has a slot (5c) for engagement, overflow and operation of the control trigger (4). The slot (5c) is established under the recess (5al) so that the trigger (3) is located under the grip handle, that is to say under the body (5a), inside protective 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 (5b 1) 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 (5b 1) faisant office de carter.The whole of the protective element (5) as defined is advantageously produced by injection of a plastic material. Note that opposite the part (5b 1) of the profiled shape (5b) acting as a sub-guard, the part (5b2), at the level of the body (5a), is full. Note also that the shapes of the profiled part (5b) acting as a sub-guard are judiciously determined so as not to alter the oscillation of the handles gripping. This is particularly the case at the connection of the lower part of the part (5b3) of the sub-guard with the part (5b 1) acting as a casing.
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 (5b 1) 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) profiled in section to cover the upper part of the head (2) and ensure a visual connection between two protective elements (5) in particular between the two parts (5b 1) serving as a housing. This connecting element (7) can be independent and attached to be fixed by any known and appropriate means at the level of 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 protectionWithout departing from the scope of the invention, an embodiment is not excluded according to which the connecting element (7) is made integral, with articulation capacity, with each of the protective elements
(5) notamment au niveau de la partie faisant office de carter (5bl), de manière à constituer un ensemble unitaire. La liaison articulée entré 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.(5) in particular at the part serving as a casing (5bl), so as to constitute a unitary assembly. The articulated connection between the connecting element (7) and each of the protective elements (5) can be obtained by any means known at the time of molding of the entire gripping system. These provisions make it possible to keep the oscillating mounting of the handles.
Compte tenu de ces dispositions, il apparaît 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. Les avantages ressortent bien de la description. In view of these provisions, it appears that the control trigger can be mounted under one of the grip handles, thus avoiding the use of an intermediate locking piece. The trigger is perfectly protected in the defined space. The same applies to the user's hands. The advantages are apparent from the description.
