Definitions
- the invention relates generally to a handling device such as a stacking cart or of a stacking devil and it relates more precisely to a single girder lifting mast.
- a handling device such as a stacking cart or of a stacking devil
- Such a mast is already shown in WO-A-84/01765.
- the frame of the trolleys equipped with lifting is usually formed by two vertical beams resting on a base and between these beams are fixed the lifting systems themselves, for example with chains, which drive forks or trays sliding on these beams.
- These vertical beams are usually formed of I and U-shaped profiles and are more or less separated from each other depending on the achievements. he is apparent that we are looking for montages that aim to avoid having to have security screens between these beams, and using two very close together, or even a single central beam enveloping moving parts and mechanisms solve this problem of security, at the same time that he gives a new aesthetic to the trolley thus produced. But this beam central must, at the same time that it lends itself to load lifting functions, confer all the strength and rigidity that can be expected from the structure of a trolley subjected to constraints difficult.
- the invention therefore relates to a lifting mast for handling device like a stacking cart
- the fixed frame consists on the one hand of a profile in folded sheet metal with a vertical oriented opening forward of the truck on the side of the load transported and on the other hand a reinforcement profile fixed to the other profile and which delimits with it a hollow box on the rear side of the mast, the inside faces of the profile constituted as a raceway for rollers with horizontal axes, carrying at least one mobile mechanism inside the mast.
- the reinforcing profile is fixed internally to the other profile and the front of the reinforcement profile serves as a raceway for rollers.
- the outer profile is shaped of U whose V-shaped base constitutes an edge vertical on the rear side of the carriage and in that towards the front, the side walls of said profile return inward by a small ledge.
- the mobile mechanism is an equipment carriage attached to a chain or strap linked to a support of attachment connected to a fixed point relative to the body of cylinder, the chain returning on a pulley coupled to the head of a cylinder rod.
- the mobile mechanism is a frame consisting of an interior telescopic beam associated with two rolling guides fitted with two rollers bearing against the reinforcement profile, and rolling on two rollers integral with the profile.
- Figure 1 an exploded view in elevation of a carriage stacker with a single central mast.
- Figure 2 a plan view of the carriage according to the figure 1.

- FIG. 5 an exploded view in elevation of a mast according to figures (3) and (4).
- Figures 1 and 2 show a carriage stacker with a single central mast designated in its together by reference 1.
- the carriage is basically made up of a base plate 2 on which is fixed the mast, and on the sides of which are bent tubes 3 bearing in their ends of the rollers 4.
- In front of the plate 2 is develop two horizontal beams 5 terminated by bits also fitted with rollers 5.
- a transverse tube reinforcement 7 extends under the base plate. Above this is fixed to a pumping lever 8 oscillating on the manual hydraulic pump 9.
- the fixed frame of the central mast is formed by a external profile 1 in folded sheet of general section in U-shape whose base is not flat but V-shaped very open which constitutes a vertical edge 10 which rises from the rear side of the cart.
- a vertical edge 10 which rises from the rear side of the cart.
- the side walls 11 of the mast return inward by a small flange 12.
- a reinforcing profile 13 which delimits a hollow box 14 on the rear side of the mast, as seen more precisely in Figure 2.
- the reinforcing profile is welded externally to the U-shaped, the main thing being that it forms a box hollow on one side of the mast.
- the internal face of the flanges 12 and the external face profiles 13 serve as raceways for two pairs of rollers 15 with horizontal axes 16, on which is mounted an equipment carriage 17, shown in low position in Figure 1, and dotted in position high.
- the carriage 17 is hooked to a chain 18 which makes back on a pulley 19 and whose opposite strand is connected to a fastening support 20 connected to a fixed point by relation to the cylinder body.
- Pulley 19 is itself mounted on a yoke 21 coupled to the head of a rod of a cylinder 22 passing through a fixed guide 23 provided at the level of attachment support 20.
- the base 24 of the jack is connected hydraulically at the pump 9.
- the lever pumping 8 ensures the lifting of the rod 22 and the yoke 21.
- the chain 18 being fixed to its attachment support 20, drives the carriage in its upward movement.

Description
L'invention se rapporte d'une façon générale à un appareil de manutention du genre d'un chariot gerbeur ou d'un diable gerbeur et elle concerne plus précisément un mât de levage monopoutre. Un tel mât est déja montré dans WO-A- 84/01765.The invention relates generally to a handling device such as a stacking cart or of a stacking devil and it relates more precisely to a single girder lifting mast. Such a mast is already shown in WO-A-84/01765.
L'ossature des chariots équipés de systèmes de levage est généralement formée de deux poutres verticales en appui sur un socle et entre ces poutres sont fixés les systèmes de levage proprement dits, par exemple à chaínes, qui entraínent des fourches ou plateaux coulissant sur ces poutres. Ces poutres verticales sont habituellement formées de profilés en forme de I et de U et sont plus ou moins écartées l'une de l'autre selon les réalisations. Il est apparent que l'on recherche des montages qui visent à éviter d'avoir à disposer des écrans de sécurité entre ces poutres, et le fait d'utiliser deux poutres très rapprochées, voire une seule poutre centrale enveloppant les parties mobiles et les mécanismes, résout ce problème de sécurité, en même temps qu'il donne une nouvelle esthétique au chariot ainsi réalisé. Mais cette poutre centrale doit, en même temps qu'elle se prête aux fonctions de levage des charges, conférer toute la solidité et la rigidité qu'on peut attendre de la structure d'un chariot soumis à des contraintes difficiles.The frame of the trolleys equipped with lifting is usually formed by two vertical beams resting on a base and between these beams are fixed the lifting systems themselves, for example with chains, which drive forks or trays sliding on these beams. These vertical beams are usually formed of I and U-shaped profiles and are more or less separated from each other depending on the achievements. he is apparent that we are looking for montages that aim to avoid having to have security screens between these beams, and using two very close together, or even a single central beam enveloping moving parts and mechanisms solve this problem of security, at the same time that he gives a new aesthetic to the trolley thus produced. But this beam central must, at the same time that it lends itself to load lifting functions, confer all the strength and rigidity that can be expected from the structure of a trolley subjected to constraints difficult.
C'est un mérite de la Demanderesse d'avoir imaginé et réalisé une structure de mât unique de levage qui répond à ces impératifs.It is a merit of the Applicant to have imagined and produced a unique lifting mast structure which meets these imperatives.
L'invention a donc pour objet un mât de levage pour appareil de manutention du genre d'un chariot gerbeur dont la charpente fixe est constituée d'une part d'un profilé en tôle pliée pourvue d'une ouverture verticale orientée vers l'avant du chariot du côté de la charge transportée et d'autre part d'un profilé de renforcement fixé à l'autre profilé et qui délimite avec lui un caisson creux du côté arrière du mât, les faces intérieures du profilé constitué servant de chemin de roulement à des galets à axes horizontaux, porteurs d'au moins un mécanisme mobile à l'intérieur du mât.The invention therefore relates to a lifting mast for handling device like a stacking cart, the fixed frame consists on the one hand of a profile in folded sheet metal with a vertical oriented opening forward of the truck on the side of the load transported and on the other hand a reinforcement profile fixed to the other profile and which delimits with it a hollow box on the rear side of the mast, the inside faces of the profile constituted as a raceway for rollers with horizontal axes, carrying at least one mobile mechanism inside the mast.
Selon un mode de réalisation préférentielle de l'invention, le profilé de renforcement est fixé intérieurement à l'autre profilé et la face avant du profilé de renforcement sert de chemin de roulement aux galets.According to a preferred embodiment of the invention, the reinforcing profile is fixed internally to the other profile and the front of the reinforcement profile serves as a raceway for rollers.
Plus précisément, le profilé extérieur est en forme de U dont la base en forme de V constitue une arête verticale du côté arrière du chariot et en ce que, vers l'avant, les parois latérales dudit profilé font retour vers l'intérieur par un petit rebord.More specifically, the outer profile is shaped of U whose V-shaped base constitutes an edge vertical on the rear side of the carriage and in that towards the front, the side walls of said profile return inward by a small ledge.
Selon une caractéristique principale de l'invention, le mécanisme mobile est un chariot porte équipements accroché à une chaíne ou une sangle liée à un support d'attache relié à un point fixe par rapport au corps de vérin, la chaíne faisant retour sur une poulie attelée à le tête d'une tige de vérin.According to a main characteristic of the invention, the mobile mechanism is an equipment carriage attached to a chain or strap linked to a support of attachment connected to a fixed point relative to the body of cylinder, the chain returning on a pulley coupled to the head of a cylinder rod.
Selon encore une autre caractéristique principale de l'invention, le mécanisme mobile est une charpente constituée d'une poutre télescopique intérieure associée à deux guides de roulage équipés de deux galets de roulement en appui contre le profilé de renforcement, et roulant sur deux galets solidaires du profilé.According to yet another main characteristic of the invention, the mobile mechanism is a frame consisting of an interior telescopic beam associated with two rolling guides fitted with two rollers bearing against the reinforcement profile, and rolling on two rollers integral with the profile.
D'autres caractéristiques particulières et les avantages de l'invention seront perçus à la lecture de la description suivante d'exemples non limitatifs de réalisation dans lesquels il est fait référence aux dessins annexés qui représentent.Other special features and advantages of the invention will be seen on reading the following description of nonlimiting examples of realization in which reference is made to attached drawings which represent.

Figure 5, une vue éclatée en élévation d'un mât selon les figures (3) et (4). Figure 5, an exploded view in elevation of a mast according to figures (3) and (4).
On a représenté aux figures 1 et 2 un chariot
gerbeur disposant d'un seul mât central désigné dans son
ensemble par la référence 1. Le chariot est
essentiellement constitué d'une plaque de base 2 sur
laquelle est fixée le mât, et sur les côtés de laquelle
sont rapportés des tubes coudés 3 portant en leurs
extrémités des roulettes 4. En avant de la plaque 2 se
développent deux longerons horizontaux 5 terminés par des
embouts également équipés de galets 5. Un tube transversal
de renfort 7 s'étend sous la plaque de base. Au dessus de
celle-ci est fixé un levier de pompage 8 oscillant sur la
pompe hydraulique manuelle 9.Figures 1 and 2 show a carriage
stacker with a single central mast designated in its
together by
La charpente fixe du mât central est formée d'un
profilé extérieur 1 en tôle pliée de section générale en
forme de U dont la base n'est pas plane mais en forme de V
très ouvert qui constitue une arête verticale 10 qui
s'élève du côté arrière du chariot. Du côté opposé c'est-à-dire
vers l'avant du chariot les parois latérales 11 du
mât font retour vers l'intérieur par un petit rebord 12.
Entre les deux rebords est ainsi ménagée dans le profilé 1
une ouverture verticale orientée vers l'avant du chariot,
c'est-à-dire du côté de la charge transportée. A
l'intérieur du mât est soudé un profilé de renforcement 13
qui délimite un caisson creux 14 du côté arrière du mât,
comme on le voit plus précisément à la figure 2.The fixed frame of the central mast is formed by a
En variante de réalisation on pourrait prévoir que le profilé de renforcement est soudé extérieurement au profilé en U, l'essentiel étant qu'il forme un caisson creux sur un côté du mât.As an alternative embodiment, provision could be made for the reinforcing profile is welded externally to the U-shaped, the main thing being that it forms a box hollow on one side of the mast.
La face interne des rebords 12 et la face externe
des profilés 13 servent de chemins de roulement à deux
paires de galets 15 à axes horizontaux 16, sur lesquels
est monté un chariot porte-équipements 17, représenté en
position basse à la figure 1, et en pointillé en position
haute. Le chariot 17 est accroché à une chaíne 18 qui fait
retour sur une poulie 19 et dont le brin opposé est relié
à un support d'attache 20 relié à un point fixe par
rapport au corps de vérin. La poulie 19 est elle-même
montée sur une chape 21 attelée à la tête d'une tige d'un
vérin 22 traversant un guide fixe 23 prévu au niveau du
support d'attache 20. La base 24 du vérin est reliée
hydrauliquement à la pompe 9.The internal face of the
Pour assurer la montée du chariot 17, le levier de
pompage 8 assure la levée de la tige 22 et de la chape 21.
La chaíne 18 étant fixée à son support d'attache 20,
entraíne le chariot dans son mouvement ascendant.To ensure the
La figure 3 illustre un autre mode de réalisation de
mât profilé 1 renfermant une poutre télescopique
intérieure 25. On retrouve un profilé voisin de celui
décrit précédemment, les mêmes éléments portant les mêmes
références. Mais à la poutre télescopique intérieure 25,
est soudé, de part et d'autre, un guide de roulage 26 en
forme de S. La poutre mobile avec ses guides forme une
charpente mobile qui peut s'élever le long du profilé fixe
grâce d'une part à deux galets de roulement 27 à axe
horizontal solidaires de la poutre mobile en appui contre
le profilé de renforcement 13, et d'autre part à deux
galets de roulement 40 à axe horizontal solidaires du
profilé 1.. Sur cette poutre 25 et à sa base est soudée
une plaque 29 qui porte les deux axes des roulements 27
ainsi que des patins de frottement 30 en appui contre la
face interne de chaque rebord 12. Des lumières 31 prévues
dans la plaque 29 renferment un basculeur 32 permettant le
réglage par l'extérieur, à l'aide des petits poussoirs 33,
du jeu de la poutre intérieure par rapport au mât.FIG. 3 illustrates another embodiment of
profiled
La figure 4 montre la section haute du mât. On
remarque que le guide de roulage 26 renferme les galets 15
du chariot porte-équipements 17 décrit en référence aux
figures 1 et 2. Le chariot est avantageusement constitué
de deux pièces en tôles découpées formant des joues sur
lesquels sont soudés les axes des galets 15. Les joues
sont assemblées entre elles par un profil 36 du type
support d'outil, en position supérieure. D'autres patins
de réglage 34 sont visibles entre la poutre 25 et le
profilé de renforcement 13.Figure 4 shows the upper section of the mast. We
note that the
En se référant également à la figure 5, on voit que
la chape 21 de la tête de vérin est fixée à la partie
haute de la poutre mobile 25. Le chariot 17 roule dans les
coulisses 26 de la charpente mobile, tiré verticalement
par la sangle 35 dont le brin opposé est accroché par un
support d'attache 20 à la base 24 du vérin c'est-à-dire à
la base de la partie fixe du mât 1. On voit que
l'extrémité supérieure de la tige mobile 22 du vérin agit
sur une chape 21 portant la poulie 19. La levée de la tige
22 entraíne par conséquent la poutre mobile 25 qui lui est
attachée, mais aussi le chariot 17 avec une vitesse de
déplacement deux fois supérieure à celle de la poutre
mobile 25 grâce au mouflage réalisé par l'ensemble poulie
19 et sangle 35, et cet ensemble télescopique autorise
donc une levée beaucoup plus importante du chariot porte-équipements,
par rapport au système décrit en référence
aux figures 1 et 2.Referring also to FIG. 5, it can be seen that
the
La structure du mât selon les exemples de réalisation précédemment décrits, intégrant un caisson creux se développant verticalement du côté arrière du chariot, lui confère une rigidité au moins équivalente à celle des deux poutres verticales de type classique. En outre le mât étant ainsi fermé à la partie arrière, c'est-à-dire du côté où se tient l'utilisateur, ce dernier ne peut intempestivement atteindre les mécanismes mobiles de levage, protégés par la coque que constitue le mât profilé, ce qui est un réel progrès sur le plan de la sécurité, et évite d'ajouter des capots ou écrans de protection. Enfin ce mât unique donne une esthétique nouvelle au chariot et pour l'utilisateur, augmente son champ de vision sur les produits transportés, et les zones de circulation et de stockage.The structure of the mast according to the examples of realization previously described, integrating a box hollow developing vertically from the rear side of the carriage, gives it a rigidity at least equivalent to that of the two vertical beams of the conventional type. In besides the mast thus being closed at the rear part, that is to say on the side where the user stands, the user does not may inadvertently reach the mobile mechanisms of lifting, protected by the hull which constitutes the mast streamlined, which is real progress in terms of safety, and avoid adding hoods or screens protection. Finally this unique mast gives an aesthetic new to the cart and for the user, increases its field of vision on the products transported, and the zones circulation and storage.
