Abstract

The foot rest (2) has a height adjustable plate (1) integrated to a carriage (3) sliding vertically on tracks (4, 5) e.g. circular tracks, where the tracks are integrated to a frame (6) of the foot rest. The carriage is supported on a push-pull tab (7) that is placed parallel to the height adjustable plate. The push-pull tab immobilizes the carriage by push-pull wedging of an opening (82) on a guidance (9) at a location irrespective to the travel of the carriage in a non actuated state so as to position the height adjustable plate at desired height.

Description

L'invention concerne un repose-pied (2) pour postes de travail d'atelier et de bureau. Selon la nature du travail et la physionomie de l'opérateur, les postes de travail, les sièges et par conséquence le plateau (1) du repose-pied doivent être ajustables en hauteur. Pour réaliser l'ajustage en hauteur du plateau (1) du repose-pied (2) on utilise couramment des systèmes d'indexage ou de coincement par vis d'appui sur colonne verticale. Cet ajustage cependant nécessite l'intervention manuelle et souvent répétitive de l'opérateur au niveau du repose-pied même, en général mal accessible sous le poste de travail ou bureau. Une solution connue utilise un système avec sur la face du plateau un poussoir qui libère l'indexage du plateau dont le poids est compensé par un ressort à gaz. Cette solution comporte le risque d'un actionnement accidentel par pose du pied inconscient sur le poussoir. En plus, le ressort à gaz représente un coût supplémentaire et une pièce à durée de vie limitée. D'autres solutions faisant appel à des télécommandes électriques, hydrauliques ou 15 mécaniques souffrent de leur coût élevé et de leur mobilité réduite ainsi d'un éventuel besoin en énergie extérieure. La présente invention, détaillé dans la suite, propose une solution simple et efficace à ce problème. The invention relates to a footrest (2) for workshop and office workstations. Depending on the nature of the work and the appearance of the operator, workstations, seats and therefore the platform (1) of the footrest must be adjustable in height. To achieve the height adjustment of the plate (1) of the footrest (2) are commonly used indexing systems or wedging by support screws on vertical column. This adjustment, however, requires the manual and often repetitive intervention of the operator at the level of the footrest itself, generally poorly accessible under the workstation or office. A known solution uses a system with on the face of the plate a pusher which releases the indexing of the plate whose weight is compensated by a gas spring. This solution involves the risk of accidental actuation by placing the unconscious foot on the pusher. In addition, the gas spring represents an additional cost and a part with a limited lifetime. Other solutions using electrical, hydraulic or mechanical remote controls suffer from their high cost and reduced mobility as well as a possible need for external energy. The present invention, detailed in the following, proposes a simple and effective solution to this problem.

20 Le plateau (1) du repose-pied (2) est solidaire d'un chariot (3) coulissant dans des pistes (4,5) sensiblement verticales et solidaires du châssis (6) du repose- pied (2). Ce chariot (3) est équipé d'une languette d'arc-boutement (7) sensiblement parallèle au plateau (1) articulé autour d'un axe (8,81) sensiblement horizontale, languette coulissant avec une ouverture (82) distant de « a » (93) de l'axe horizontale (8,81) sur un guidage 25 linéaire (9) parallèle aux pistes (4,5) solidaire du châssis (6) du repose-pied (2). En état de repos la languette (7) est inclinée d'un angle « ç » (71) contre le plateau (1) d'une façon telle que son ouverture (82) se coince par arc-boutement sur le guidage linéaire (9) et de ce fait empêche le chariot (3) de coulisser dans ses pistes (4,5). Cette inclinaison « (p » (71) de la languette (7) peut être soutenue par la force d'un ressort (10) ou d'un 30 contrepoids (11). Pour monter le niveau du plateau (1) il suffit de soulever la languette (7) avec la pointe du pied ou la main pour débloquer la languette (7) et de monter le plateau avec la force de la pointe du pied ou de la main. Une fois le niveau souhaité atteint, il suffit de retirer rapidement le bout du pied ou la main pour que la languette (7) retourne dans sa position 35 inclinée de l'angle « cp » (71) et bloque ainsi le chariot (3) à la hauteur correspondante. Pour descendre le niveau du plateau (1) il suffit de soulever la languette (7) avec le bout du pied ou la main pour débloquer la languette (7) et de laisser descendre le plateau (1) par son propre poids. Une fois le niveau souhaité atteint, il suffit de retirer rapidement le bout du pied ou la main pour que la languette (7) retourne dans sa position inclinée de l'angle « tp » (71) et bloque ainsi le chariot (3) à la hauteur correspondante. Les pistes (4,5) peuvent être de section circulaire, de section en U ou de section en I, le châssis (6) du repose-pied même peut être solidaire du poste de travail qu'il équipe ou d'un support sensiblement immobile relatif à ce poste ou d'un socle (61) reposant sur le sol. The platform (1) of the footrest (2) is integral with a carriage (3) sliding in tracks (4,5) substantially vertical and integral with the frame (6) of the footrest (2). This carriage (3) is equipped with an arching tongue (7) substantially parallel to the plate (1) hinged about a substantially horizontal axis (8, 81), a sliding tongue with an opening (82) remote from "A" (93) of the horizontal axis (8,81) on a linear guide (9) parallel to the tracks (4,5) integral with the frame (6) of the footrest (2). In the state of rest, the tongue (7) is inclined at an angle "ç" (71) against the plate (1) in such a way that its opening (82) is jammed by jamming on the linear guide (9). ) and thus prevents the carriage (3) from sliding in its tracks (4,5). This inclination "(p" (71) of the tongue (7) can be supported by the force of a spring (10) or a counterweight (11) .To raise the level of the plate (1) it is sufficient to lift the tongue (7) with the tip of your foot or the hand to unlock the tongue (7) and mount the platform with the force of the tip of the foot or hand.When the desired level is reached, simply remove quickly the tip of the foot or the hand so that the tongue (7) returns to its inclined position of the angle "cp" (71) and thus blocks the carriage (3) to the corresponding height. (1) simply lift the tongue (7) with the tip of the foot or the hand to unlock the tongue (7) and let the tray (1) by its own weight.After the desired level reached, it is sufficient quickly remove the tip of the foot or the hand so that the tongue (7) returns to its inclined position of the angle "tp" (71) and blocks i the carriage (3) at the corresponding height. The tracks (4, 5) may be of circular section, of U-section or I-section, the frame (6) of the footrest itself may be integral with the workstation that it equips or a support substantially stationary relative to this station or a base (61) resting on the ground.

Fig.1 montre une vue en perspective d'un repose pied selon la description ci-dessus dont le guidage linéaire (9) est matérialisé par une tige à section circulaire et l'ouverture (82) de la languette (7) par un perçage d'un diamètre légèrement plus grand que le diamètre de la tige. Fig. 2 montre le principe de fonctionnement de Fig. 1 en plan yz. Fig. 3 montre un détail de Fig. 2 pour visualiser le principe de rotation de la languette 15 (7) autour de son axe horizontal (8,81) et le coincement par arc-boutement sur son guidage linéaire (9) Fig. 4 montre le détail d'une variante du repose-pied caractérisé par le fait que les pistes (4,5) sont matérialisées par des profilés en section de U (41) dans lesquelles coulisse le chariot (3) et l'ouverture (82) de la languette (7). Les pistes (4,5) du chariot (3) 20 et le guidage linéaire (9) de la languette d'arc-boutement (7) sont ainsi identiques. Fig.1 shows a perspective view of a footrest as described above, the linear guide (9) is embodied by a circular section rod and the opening (82) of the tongue (7) by a drilling a diameter slightly larger than the diameter of the stem. Fig. 2 shows the operating principle of FIG. 1 in plan yz. Fig. 3 shows a detail of FIG. 2 to visualize the principle of rotation of the tongue 15 (7) around its horizontal axis (8,81) and jamming by riveting on its linear guide (9). 4 shows the detail of a variant of the footrest characterized in that the tracks (4,5) are materialized by U-section profiles (41) in which slides the carriage (3) and the opening (82). ) of the tongue (7). The tracks (4,5) of the carriage (3) 20 and the linear guide (9) of the bracing tongue (7) are thus identical.
