ENSEMBLE DE PESAGE ADAPTABLE A UN APPAREIL DE LEVAGE DESCRIPTIONWEIGHING ASSEMBLY ADAPTABLE TO A LIFTING APPARATUS DESCRIPTION
DOMAINE DE L'INVENTION L'invention concerne un ensemble de pesage de charges diverses adaptable à un appareil à bras de levage tubulaire pourvu, à son extrémité, d'un moyen de préhension de la charge à lever et à peser du type à crochet, à plateau ou à harnais. FIELD OF THE INVENTION The invention relates to a weighing assembly of various loads adaptable to a tubular lifting arm apparatus provided at its end with a means for gripping the load to be lifted and weighed of the hook type, with plate or harness.
Souhaiter peser une charge que l'on soulève correspond à une situation que l'on rencontre dans différents domaines comme par exemple dans les milieux médicalisés où l'on utilise un lève-malade qui constitue la seule solution pour le déplacer et pour le peser si besoin est. Wishing to weigh a load that is raised corresponds to a situation that is encountered in different areas such as for example in medical settings where we use a patient lift that is the only way to move and weigh it if need is.
RESUME DE L'INVENTION L'invention vise à réaliser un ensemble de pesage, de conception simple, facilement adaptable à un appareil de levage à bras tubulaire et constituant une solution inédite et originale apte à répondre au problème posé. SUMMARY OF THE INVENTION The object of the invention is to provide a weighing assembly of simple design, easily adaptable to a tubular arm lifting device and constituting an original and novel solution able to respond to the problem posed.
Elle concerne à cet effet, un ensemble de pesage qui se caractérise essentiellement en ce qu'il est constitué d'un capteur de poids et d'un support qui sont intercalés entre le bras de levage et le moyen de préhension et qui sont placés à l'intérieur de l'extrémité dudit bras de levage. It relates for this purpose, a weighing assembly which is essentially characterized in that it consists of a weight sensor and a support which are interposed between the lifting arm and the gripping means and which are placed at the inside of the end of said lifting arm.
Selon des particularités de réalisation de l'invention: - le support du capteur de poids possède un profil extérieur dont la forme et les dimensions sont adaptées pour permettre son emboîtement dans le profil intérieur du bras de levage; - un indicateur de poids est fixé au support du capteur de poids à l'extérieur de l'extrémité dudit bras de levage. According to particular features of the invention: the support of the weight sensor has an outer profile whose shape and dimensions are adapted to allow it to fit into the internal profile of the lifting arm; a weight indicator is attached to the weight sensor support outside the end of said lifting arm.
- la liaison entre l'extrémité du capteur de poids et le moyen de préhension de la charge, est assurée au moyen d'une pièce qui traverse la partie inférieure du bras de levage. the connection between the end of the weight sensor and the means for gripping the load is ensured by means of a part which passes through the lower part of the lifting arm.

DESCRIPTION DETAILLEE DE L'INVENTION DETAILED DESCRIPTION OF THE INVENTION
L'ensemble de pesage de charges diverses (représenté aux figures 2, 3 et 4) est adaptable à un appareil de levage (représenté à la figure 1) à bras tubulaire (1) pourvu, à son extrémité, d'un moyen (2) de préhension de la charge à soulever et à peser fixé au bras (1) au moyen d'écrous et de rondelles (2A). The set of weighing various loads (shown in Figures 2, 3 and 4) is adaptable to a lifting device (shown in Figure 1) with tubular arm (1) provided at its end, means (2 ) gripping the load to lift and weigh fixed to the arm (1) by means of nuts and washers (2A).
Il est constitué d'un capteur de poids (3) et d'un support (4) qui sont intercalés entre le bras de levage (1) et le moyen de préhension (2) et qui sont placés à l'intérieur de l'extrémité dudit bras de levage (1). It consists of a weight sensor (3) and a support (4) which are interposed between the lifting arm (1) and the gripping means (2) and which are placed inside the end of said lifting arm (1).
Le support (4) du capteur de poids (3) possède un profil extérieur dont la forme et les dimensions sont adaptées pour permettre son emboîtement dans le profil intérieur du bras de levage (1). The support (4) of the weight sensor (3) has an outer profile whose shape and dimensions are adapted to allow it to fit into the inner profile of the lifting arm (1).
L'ensemble de pesage comporte également un indicateur de poids (5) qui est fixé au support (4) du capteur de poids (3) à l'extérieur de l'extrémité du bras de levage (1). La liaison entre l'extrémité du capteur de poids (3) et le moyen (2) de préhension de la charge, est assurée au moyen d'une pièce (6) qui traverse la partie inférieure du bras de levage (1). The weighing assembly also includes a weight indicator (5) which is attached to the weight sensor support (4) (3) outside the end of the lift arm (1). The connection between the end of the weight sensor (3) and the means (2) for gripping the load is ensured by means of a part (6) which passes through the lower part of the lifting arm (1).
La mise en place de la pièce de liaison (6) peut utiliser les ouvertures (1A) et (1B) du bras (1) prévues pour positionner et fixer initialement le moyen (2) de préhension de la charge à soulever. The establishment of the connecting piece (6) can use the openings (1A) and (1B) of the arm (1) provided for positioning and initially fix the means (2) for gripping the load to be lifted.
La pièce de liaison (6) comporte un dispositif, du type cardan (6A), câble (6B) ou rondelles sphériques (6C), permettant de désaccoupler l'effort (F) de la charge. The connecting piece (6) comprises a device, of the cardan type (6A), cable (6B) or spherical washers (6C), for uncoupling the force (F) of the load.
Elle est maintenue au capteur de poids (3) au moyen d'un ensemble écrou et rondelle (6D). It is held at the weight sensor (3) by means of a nut and washer assembly (6D).
L'indicateur de poids (5) comporte un emplacement (5A) destiné à contenir une source 30 d'énergie autonome, un afficheur (5B) et des boutons de commande (5C). Le capteur de poids (4) peut être fixé au socle (4) au moyen de vis (7). The weight indicator (5) has a location (5A) for holding an autonomous power source, a display (5B) and control buttons (5C). The weight sensor (4) can be fixed to the base (4) by means of screws (7).
L'indicateur de poids (5) peut être fixé au socle (4) au moyen de vis (8). The weight indicator (5) can be fixed to the base (4) by means of screws (8).
Le bras tubulaire peut être réalisé au moyen d'un profilé extrudé. The tubular arm can be made by means of an extruded profile.
2891622 3 Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits et représentés pour lesquels on pourra prévoir d'autres variantes, en particulier dans: - le type d'appareil de levage, de profil de bras de levage et de moyen de préhension de la charge; - le type de capteur de poids, d'indicateur de poids, de support et de pièce de liaison; - le type de dispositif permettant de désaccoupler la charge; et l'étendre à d'autres applications; sans pour cela sortir du cadre de l'invention. Of course, the invention is not limited to the embodiments described and shown for which other variants may be provided, in particular in: the type of lifting device, lifting arm profile and gripping means of the load; - the type of weight sensor, weight indicator, support and connecting piece; - the type of device used to uncouple the load; and extend it to other applications; without departing from the scope of the invention.
