Abstract
Description
L'invention concerne un dispositif d'accouplement basculant, notamment pour lever des brouettes, ce dispositif pouvant être monté et mis en position de travail simplement en l'introduisant dans un siège approprié, et pouvant être démonté et basculé de façon tout aussi simple. The invention relates to a tilting coupling device, in particular for lifting wheelbarrows, this device being able to be mounted and put in working position simply by inserting it in an appropriate seat, and being able to be dismantled and tilted in just as simple manner.
I1 est frequemment nécessaire, par exemple sur les chantiers de bâtiments, de lever une brouette au moyen de grues ou d'engins similaires. Il faut pour cela un dispositif d'accouplement capable de maintenir la brouette chargée en équilibre pendant le levage de cette brouette. It is frequently necessary, for example on building sites, to lift a wheelbarrow by cranes or similar equipment. This requires a coupling device capable of keeping the loaded wheelbarrow in balance during the lifting of this wheelbarrow.
Un tel dispositif est de préférence basculant, parce qutun châssis fixe dispose au-dessus de la benne constitumit un obstacle pendant les opérations de chargement et de déchargement. Such a device is preferably tiltable, because a fixed frame has an obstacle above the grab constituting an obstacle during the loading and unloading operations.
I1 est également judicieux de réaliser un dispositif facile à monter et à démonter au moyen d'un petit nombre dopérationstsimpless afin de faciliter le remplissage et le transport de la brouette. It is also wise to make a device that is easy to assemble and disassemble by means of a small number of simple operations in order to facilitate filling and transporting the wheelbarrow.
Ce qui précède montre que le problème à résoudre consiste à constituer un dispositif mobile capable de passer aisément d'une position de stockage dans une position de travail dans laquelle il est fermement ancré sur la brouette. The above shows that the problem to be solved consists in constituting a mobile device capable of easily passing from a storage position into a working position in which it is firmly anchored on the wheelbarrow.
L'invention concerne à cet effet un dispositif du type ci-dessus caractérisé en ce qu'il est essentiellement constitué par un châssis rigide ouvert, dans lequel deux couples de tourillons en saillie sur les extrémités du châssis s'ajustent dans des sièges disposés dans des plaques, de préférence en toue, fixées au chassies de la brouette
Ltarrangement des éléments ci-dessus conjointement avec la forme particulière des sièges forme un mécanisme d'accouplement qui, lorsque la brouette repose sur son support, est à tus égards un verrouillage évitant la rotation, tandis qu'il permet le basculement du châssis lorsque le support ne porte pas la brouette.To this end, the invention relates to a device of the above type, characterized in that it is essentially constituted by an open rigid frame, in which two pairs of pins projecting from the ends of the frame fit into seats arranged in plates, preferably in shape, attached to the barrow
The arrangement of the above elements together with the particular shape of the seats forms a coupling mechanism which, when the wheelbarrow rests on its support, is in many respects an interlock preventing rotation, while it allows the chassis to tilt when the support does not carry the wheelbarrow.
L'invention sera mieux comprise en regard de la description ci-après et des dessins annexés représentant un exemple de réalisation de l'invention, dessins dans lesquels
- la figure 1 est une vue en perspective d'une brouette sur laquelle est monté le dispositif conforme à l'invention,
- la figure 2 représente le châssis du dispositif conforme à l'invention,
- la figure 3 représente une plaque dans laquelle est réalisé un siège pour l'introduction du dispositif suivant la figure 2,
- les figures 3a, 3b, 3c représentent les différentes positions que peut prendre le châssis de la figure 2 par rapport à la plaque de la figure 3.The invention will be better understood with reference to the description below and to the accompanying drawings showing an embodiment of the invention, drawings in which
FIG. 1 is a perspective view of a wheelbarrow on which the device according to the invention is mounted,
FIG. 2 represents the chassis of the device according to the invention,
FIG. 3 represents a plate in which a seat is made for the introduction of the device according to FIG. 2,
- Figures 3a, 3b, 3c represent the different positions that the chassis of Figure 2 can take relative to the plate of Figure 3.
Le dispesitif conforme à l'invention est essentiellement cnnstitué par un châssis rigide ouvert 1 (figure 2) dont les extrémités 2 et 3 comportent deux couples de tourillons 4 et 5, 4' et 5' présentant des extrémités intérieures élargies. The device according to the invention is essentially constituted by an open rigid frame 1 (FIG. 2), the ends 2 and 3 of which comprise two pairs of pins 4 and 5, 4 ′ and 5 ′ having enlarged internal ends.
A la partie supérieure du dispositif est monté un anneau 9 ou un organe similaire pour assurer l'accouplement avec un organe de levage. At the upper part of the device is mounted a ring 9 or a similar member for coupling with a lifting member.
Deux plaques 6 (figure 3), de préférence en t & e ou matière similaire, sont soudées ou-fixées dtune autre manière au chassies de la brouette, un siège pour le logement des tourillons 4 et 5 ou 4' et 5' étant réalisé dans chaque plaque. Two plates 6 (FIG. 3), preferably made of t & e or similar material, are welded or fixed in another way to the chases of the wheelbarrow, a seat for housing the pins 4 and 5 or 4 ′ and 5 ′ being produced. in each plate.
Le siège 10 est légèrement plus large que les tourillons 4, 5 et plus étroit que les extrémités élargies de ces tourillons. Il a une forme allongée essentiellement verticale et est défini par deux-petites languettes 7 et 8. The seat 10 is slightly wider than the pins 4, 5 and narrower than the widened ends of these pins. It has an elongated essentially vertical shape and is defined by two small tabs 7 and 8.
H' désigne la longueur de la languette 7, H" la longueur de la languette S. On a désigné par H"' la distance entre les extrémités des languettes e par H la distance entre les axes des tourillons 4 et 5. La distance H"' est supérieure ou égale au diamètre des tourillons 4 et 5. H 'denotes the length of the tongue 7, H "the length of the tongue S. The distance between the ends of the tongues is designated by H"' e by H the distance between the axes of the pins 4 and 5. The distance H "'is greater than or equal to the diameter of pins 4 and 5.
La distance H est égale ou légèrement supérieure à Ht et supérieure à H" * H"'. The distance H is equal to or slightly greater than Ht and greater than H "* H" '.
Ainsi, lorsque le châssis 1 est déchargé (figure 3b), les tourillons 5 et 5' reposent au fond de leurs sièges respectifs. Les tourillnns 4 et 4' sont dans une position cvrrespondant à l'intervalle existant entre les languettes. Il est en conséquence possible de basculer le châssis 1 (figure 3c) car celui-ci est articulé autour de l'axe des broches 5 et 5r. Thus, when the chassis 1 is unloaded (Figure 3b), the pins 5 and 5 'rest at the bottom of their respective seats. The pins 4 and 4 'are in a position corresponding to the gap between the tongues. It is therefore possible to tilt the chassis 1 (Figure 3c) because it is articulated around the axis of the pins 5 and 5r.
Si, au contraire, le châssis 1 (figure 3a) est levé en position verticale, les parois du siège 10 empêchent tout déplacement des tourillons. Un assemblage de verrouillage est ainsi formé pour éviter que la brouette oscille lorsque la charge est suportée par l'anneau 9.If, on the contrary, the chassis 1 (FIG. 3a) is raised in the vertical position, the walls of the seat 10 prevent any displacement of the pins. A locking assembly is thus formed to prevent the wheelbarrow from oscillating when the load is supported by the ring 9.
En disposant les plaques 6 dans une position appropriée, le centre de gravité de l'ensemble est placé au-dessous de l'anneau d'accrochage 9, ce qui permet d'obtenir un équilibre stable. By placing the plates 6 in an appropriate position, the center of gravity of the assembly is placed below the attachment ring 9, which makes it possible to obtain a stable balance.
Si cela est nécessaire, le châssis 1 peut être retiré simplement en amenant les tourillons 5 et 52 en contact avec la partie inférieure du siège 10, en faisant tourner le châssis de manière à faire passer les tourillons 4 et 4' à travers ltouverture définie par les languettes 7 et 8 et en retirant le châssis après enlèvement des tourillons 5 et 5'. If necessary, the frame 1 can be removed simply by bringing the pins 5 and 52 into contact with the lower part of the seat 10, by rotating the frame so as to pass the pins 4 and 4 'through the opening defined by the tabs 7 and 8 and removing the chassis after removing the pins 5 and 5 '.
