Les tables élévatrices en ciseau sont en général composées d'un plateau porté par 2 jambes articulées sous celui-ci et 2 jambes roulant sous celui-ci, les jambes se croisant entre elles selon une articulation horizontale transverse. Scissor lift tables are generally composed of a platform carried by 2 legs articulated under it and 2 legs rolling under it, the legs crossing each other according to a horizontal transverse articulation.
Le plateau ne peut dès lors être centré par rapport aux jambes à toutes les hauteurs et impose pour la stabilité d'avoir une structure au sol, limitant les possibilités de déplacement. The tray cannot therefore be centered with respect to the legs at all heights and requires stability to have a structure on the ground, limiting the possibilities of movement.
La présente invention est particulièrement adaptée aux tables élévatrices sans châssis au sol, sans porte-à-faux et déplaçables. The present invention is particularly suitable for lifting tables without chassis on the ground, without overhang and movable.
Elle est particulièrement adaptée aux tables pour animaux mais peut- être utilisée dans tous autres domaines. It is particularly suitable for tables for animals but can be used in all other areas.
Elle est représentée sur la figure 1. It is shown in Figure 1.
La table comporte essentiellement un plateau (9) de hauteur variable des jambes (15) et (16), un moyen d'actionnement (12) et un système d'appui au sol. The table essentially comprises a plate (9) of variable height of the legs (15) and (16), an actuating means (12) and a support system on the ground.
Le plateau (9) a à sa partie inférieure deux rails (10) longitudinaux horizontaux, par exemple deux cornières dont un plat est horizontal et un plat vertical, les plats verticaux étant traversés sensiblement en leur milieu par un axe transversal horizontal (8). The plate (9) has at its lower part two horizontal longitudinal rails (10), for example two angles of which a flat is horizontal and a vertical flat, the vertical dishes being traversed substantially in their middle by a horizontal transverse axis (8).
Le système de jambes (15) et (16) supporte le plateau par l'intermédiaire de galets ou patins (11) à axe transverse horizontaux (4) et (5), les jambes (15) et (16) se croisant selon articulation transverse horizontale (1) et transmettant les charges au sol. The system of legs (15) and (16) supports the plate by means of rollers or skids (11) with horizontal transverse axis (4) and (5), the legs (15) and (16) crossing according to articulation horizontal transverse (1) and transmitting the loads to the ground.
Les articulations 4 et 5 sont sensiblement à la même distance de l'articulation 1. The joints 4 and 5 are substantially the same distance from the joint 1.
Les jambes 15 et 16 sont chacune au nombre de un ou de deux. The legs 15 and 16 are each one or two in number.
Le moyen d'actionnement de hauteur (12) contrôle directement ou indirectement l'angulation entre les jambes (15) et (16). The height actuating means (12) directly or indirectly controls the angulation between the legs (15) and (16).
Les axes (4) et (5) des galets ou patins (11) se déplacent selon les rails 10 en sens inverse l'un de l'autre lorsque (12) fonctionne. The axes (4) and (5) of the rollers or pads (11) move along the rails 10 in opposite directions to each other when (12) is operating.
Les galets supportent la charge du plateau par exemple par la partie horizontale des cornières et guident latéralement le plateau sur la partie verticale des cornières. The rollers support the load of the plate for example by the horizontal part of the angles and laterally guide the plate on the vertical part of the angles.
<Desc/Clms Page number 2> <Desc / Clms Page number 2>
Les jambes (15) et (16) comportent des articulations (6) et (7) horizontales transverses situées entre et dans l'alignement (1) et (5) et entre et dans l'alignement (1) et (4) respectivement, par exemple au milieu. The legs (15) and (16) have transverse horizontal joints (6) and (7) located between and in alignment (1) and (5) and between and in alignment (1) and (4) respectively , for example in the middle.
Les rails (11) comportent une articulation horizontale transverse (8) sensiblement dans le plan horizontal des axes des galets (4) et (5) lorsqu'ils reposent sur ceux-ci. The rails (11) have a transverse horizontal articulation (8) substantially in the horizontal plane of the axes of the rollers (4) and (5) when they rest thereon.
Des biellettes longitudinales obliques (20) et (21) réunissent l'articulation (8) des rails aux articulations (6) et (7) des jambes, les articulations (1) (6) (8) (7) forment sensiblement un parallélogramme déformable. Oblique longitudinal links (20) and (21) join the articulation (8) of the rails to the articulations (6) and (7) of the legs, the articulations (1) (6) (8) (7) substantially form a parallelogram deformable.
Les biellettes (20) et (21) fixent la position longitudinale du plateau et le plaquent sur les galets (11). Il y a par exemple deux biellettes (20) jointives aux jambes 15 et une biellette (21) sur un axe reliant les deux jambes (16). The links (20) and (21) fix the longitudinal position of the plate and press it on the rollers (11). There are for example two links (20) contiguous to the legs 15 and a link (21) on an axis connecting the two legs (16).
Par exemple : (6) est le milieu de (1) (5) (7) est le milieu de (1) (3) et les biellettes ont la moitié de la longueur de (1) (5) ou (1) (3) et (1) (6) (8) (7) est sensiblement un losange. For example: (6) is the middle of (1) (5) (7) is the middle of (1) (3) and the links are half the length of (1) (5) or (1) ( 3) and (1) (6) (8) (7) is substantially a rhombus.
Dans la pratique, il est préférable d'avoir une force d'application du plateau sur les galets supérieure au poids du plateau, c'est-à-dire une tension sur l'une au moins des biellettes. In practice, it is preferable to have a force for applying the plate to the rollers greater than the weight of the plate, that is to say a tension on at least one of the links.
Par exemple les jambes 15 et 16 sont chacune au nombre de deux et réunies par des entretoises horizontales transverses respectivement (17) (19) et (15) (25) (26) formant 2 cadres articulés selon l'axe (1). For example, the legs 15 and 16 are each two in number and joined by transverse horizontal spacers respectively (17) (19) and (15) (25) (26) forming 2 frames articulated along the axis (1).
L'articulation (8) est placée légèrement en dessus du plan horizontal des articulations (4) et (5) ou la longueur de biellettes (20) et (21) est légèrement inférieure à la moitié des longueurs (1) (5) et (1) (4) ou le câble enserrant (1) (6) (8) (7), est tendu, la traction étant compensée par une certaine élasticité de l'ensemble, par exemple par l'élasticité des axes (7) et (8), reliant les 2 jambes (16) et les 2 rails (10) la biellette (21) étant par exemple articulée sensiblement au milieu de ceux-ci. The joint (8) is placed slightly above the horizontal plane of the joints (4) and (5) or the length of the links (20) and (21) is slightly less than half the lengths (1) (5) and (1) (4) or the enclosing cable (1) (6) (8) (7), is tensioned, the traction being compensated by a certain elasticity of the assembly, for example by the elasticity of the axes (7) and (8), connecting the 2 legs (16) and the 2 rails (10) the link (21) being for example articulated substantially in the middle of these.
<Desc/Clms Page number 3> <Desc / Clms Page number 3>
Les jambes (15) et (16) sont droites ou coudées les angles (5) (1) (3) et (4) (1) (2) étant alors inférieurs à 1800 et de concavité dirigée vers le haut. The legs (15) and (16) are straight or bent the angles (5) (1) (3) and (4) (1) (2) then being less than 1800 and of concavity directed upwards.
Le moyen d'actionnement de hauteur est par exemple constitué par un vérin agissant entre l'axe (13) fixé par l'intermédiaire de la patte (18) à l'entretoise (17) entre les jambes (15) d'une part et entre l'axe (14) fixé par l'intermédiaire de la patte (19) à l'entretoise (28) entre les jambes (16) d'autre part. The height actuating means is for example constituted by a jack acting between the axis (13) fixed by means of the tab (18) to the spacer (17) between the legs (15) on the one hand and between the axis (14) fixed by means of the tab (19) to the spacer (28) between the legs (16) on the other hand.
En variante le moyen d'actionnement peut également être fixé entre le plateau et une jambe ou une biellette ou entre une jambe et une biellette ou entre deux biellettes. As a variant, the actuating means can also be fixed between the plate and a leg or a link or between a leg and a link or between two links.
La (les) jambes (16) est (sont) munie (s) de roues (27) antidérapantes tournant librement sur l'axe (2) et roulant sur le sol. The (the) legs (16) is (are) provided (s) with non-slip wheels (27) freely rotating on the axis (2) and rolling on the ground.
La (les) jambes (15) comporte (nt) articulation transverse horizontale (3) telles que les distances (1) (3) et (1) (2) soient sensiblement les mêmes, s'articulant sur support (22) selon articulation (3) à hauteur sensiblement égale au rayon des roues (27). The (the) legs (15) have (s) horizontal transverse articulation (3) such that the distances (1) (3) and (1) (2) are substantially the same, being articulated on support (22) according to articulation (3) at a height substantially equal to the radius of the wheels (27).
Le support (22) est constitué par exemple par des dés ou par un polygone à roulettes blocables ou par des roues blocables. The support (22) is constituted for example by dice or by a polygon with lockable rollers or by lockable wheels.
En variante, les jambes 15 peuvent porter directement au sol et ont un profil de portée (22) sensiblement symétrique de celui de la roue (27) par rapport au plan vertical transverse passant par l'axe (1). As a variant, the legs 15 can bear directly on the ground and have a bearing profile (22) substantially symmetrical with that of the wheel (27) relative to the transverse vertical plane passing through the axis (1).
Le profil (22) est par exemple réalisé en roue d'axe (3) et de diamètre voisin de celui des roues (27), les roues (22) étant bloquées sur les jambes (15). The profile (22) is for example made on a wheel with an axis (3) and a diameter close to that of the wheels (27), the wheels (22) being locked on the legs (15).
Les roues sont en matériau antidérapant. The wheels are made of non-slip material.
Les roues (22) ont de préférence le perçage d'axe (3) excentré et peuvent être tournées sur elles-mêmes pour compenser les inégalités du sol avant blocage par serrage axial par exemple. The wheels (22) preferably have the axis bore (3) eccentric and can be turned on themselves to compensate for unevenness of the ground before blocking by axial clamping for example.
Le système de jambes (15) comporte à sa partie inférieure une roulette (24) sensiblement dans l'axe longitudinal de la table fixée par exemple à une patte (34) solidaire de ou réglable ou pivotant avec butée sur la traverse inférieure (25). The leg system (15) has at its lower part a caster (24) substantially in the longitudinal axis of the table fixed for example to a leg (34) integral with or adjustable or pivoting with stop on the lower crosspiece (25) .
La roulette (24) est en matériau glissant et constitue l'unique appui au sol des jambes (15) lorsque la table est en position très haute. The caster (24) is made of a sliding material and constitutes the sole support on the ground of the legs (15) when the table is in a very high position.
<Desc/Clms Page number 4> <Desc / Clms Page number 4>
Le support 22 est alors soulevé du sol. Le plateau (9) peut être fixé directement aux rails (10). The support 22 is then lifted from the ground. The plate (9) can be fixed directly to the rails (10).
En variante, les rails peuvent être réunis par des entretoises (23) formant un cadre sous lequel est fixé par la patte (32) un moyen d'actionnement d'inclinaison (33) dont l'autre extrémité est fixée au plateau (31), faisant pivoter le plateau autour de l'axe transverse (30).Alternatively, the rails can be joined by spacers (23) forming a frame under which is fixed by the lug (32) an inclination actuating means (33) the other end of which is fixed to the plate (31) , pivoting the plate around the transverse axis (30).
