Description

"DISPOSITIF ET PROCEDE DE FIXATION D'UN EQUIPEMENT TECHNIQUE SUR LE PLANCHER DE L'HABITACLE D'UN VEHICULE AUTOMOBILE"  "DEVICE AND METHOD FOR FASTENING A TECHNICAL EQUIPMENT ON THE FLOOR OF THE INTERIOR OF A MOTOR VEHICLE"
[0001 ] La présente invention concerne un dispositif de fixation d'un équipement technique sur le plancher situé dans l'habitacle d'un véhicule, notamment automobile. [0002] Un tel équipement technique peut être constitué à titre d'exemple par une batterie électrique, un boîtier électronique, une boîte à outils ou tout autre type d'équipement électrique. The present invention relates to a device for fixing a technical equipment on the floor located in the passenger compartment of a vehicle, including automobile. Such technical equipment may be constituted as an example by an electric battery, an electronic box, a toolbox or any other type of electrical equipment.
[0003] Les figures 1 à 3 représentent un dispositif connu de fixation d'un équipement électrique 1 , qui est constitué dans le cas présent par une batterie électrique, sur le plancher 2 situé dans l'habitacle d'un véhicule automobile. Figures 1 to 3 show a known device for fixing an electrical equipment 1, which is constituted in this case by an electric battery on the floor 2 located in the passenger compartment of a motor vehicle.
[0004] Le plancher 2 du véhicule comprend une traverse 3 s'étendant transversalement à la direction longitudinale du véhicule et disposée entre deux longerons parallèles 4 du plancher 2, l'un des longerons 4 étant situé à proximité d'un tunnel central 5 s'étendant longitudinalement au véhicule et servant de passage à une tubulure d'échappement des gaz de combustion du moteur thermique du véhicule. The floor 2 of the vehicle comprises a cross member 3 extending transversely to the longitudinal direction of the vehicle and disposed between two parallel members 4 of the floor 2, one of the longitudinal members 4 being located near a central tunnel 5 s extending longitudinally to the vehicle and serving as a passage for an exhaust pipe of the combustion gases of the engine of the vehicle.
[0005] La traverse 3 est une traverse d'assise supportant le siège du conducteur ou du passager avant du véhicule et un espace est ménagé entre le dessous de l'assise du siège et le plancher 2 du véhicule pour loger la batterie électrique 1 présentant une forme générale de parallélépipède rectangle relativement plat. [0006] Généralement, la fixation de la batterie électrique 1 sur le plancher 2 du véhicule s'effectue par trois points de fixation symbolisés par P1 , P2 et P3 en figure 3 situés en partie inférieure de la batterie électrique 1 . Les deux points de fixation P1 et P2 peuvent être constitués par deux pattes de fixation (non représentées) solidaires d'un côté de la batterie électrique 1 au voisinage immédiat de la partie d'extrémité du longeron 4 adjacent au tunnel central 5, tandis que l'autre point de fixation P3 peut être constitué par une patte 9 solidaire du côté de la batterie électrique 1 parallèle à la traverse 3 à l'opposé de celle-ci. Au moins une vis de fixation 10 traverse la patte 9 pour la solidariser au plancher 2. The cross member 3 is a cross member supporting the seat of the driver or front passenger of the vehicle and a space is provided between the underside of the seat and the floor 2 of the vehicle to house the electric battery 1 having a general shape of relatively flat rectangular parallelepiped. Generally, the attachment of the electric battery 1 on the floor 2 of the vehicle is effected by three fixing points symbolized by P1, P2 and P3 in Figure 3 located in the lower part of the electric battery 1. The two fixing points P1 and P2 may be constituted by two fixing lugs (not shown) integral with one side of the electric battery 1 in the immediate vicinity of the end portion of the spar 4 adjacent to the central tunnel 5, while the other fixing point P3 may be constituted by a lug 9 secured to the side of the electric battery 1 parallel to the cross member 3 opposite it. At least one fastening screw 10 passes through the tab 9 to secure it to the floor 2.
[0007] Si le point de fixation P3 est aisément accessible à un opérateur en bord de ligne de fabrication du véhicule pour fixer à l'aide d'une visseuse la patte correspondante au plancher 2 du véhicule, il n'en est pas de même pour les points de fixation P1 et P2 qui sont pratiquement inaccessibles pour l'opérateur positionné sur le côté droit du véhicule et penché en avant au-dessus du plancher 2. If the fixing point P3 is easily accessible to an operator at the edge of the vehicle manufacturing line to fix with a screwdriver the corresponding tab floor 2 of the vehicle, it is not the same for the fixing points P1 and P2 which are virtually inaccessible to the operator positioned on the right side of the vehicle and leaning forward over the floor 2.
[0008] Ainsi, ce dispositif connu de fixation de la batterie électrique 1 sur le plancher 2 du véhicule impose à l'opérateur une posture ergonomique défavorable pour visser la batterie 1 à ses trois points de fixation à l'aide de la visseuse. En outre, ce dispositif augmente le temps de montage de la batterie électrique 1 sur le plancher 2 du véhicule à cause de l'inaccessibilité de deux de ces points de fixation au plancher 2, impliquant un montage en aveugle ou, en tout cas, avec faible visibilité sur la zone de fixation. Thus, this known device for fixing the electric battery 1 on the floor 2 of the vehicle requires the operator unfavorable ergonomic position to screw the battery 1 at its three attachment points using the screwdriver. In addition, this device increases the mounting time of the electric battery 1 on the floor 2 of the vehicle because of the inaccessibility of two of these fixing points to the floor 2, involving a blind assembly or, in any case, with low visibility on the attachment area.
[0009] La présente invention a pour but de pallier les inconvénients de l'art antérieur ci- dessus décrit. The present invention aims to overcome the disadvantages of the prior art described above.

[0020] L'invention va être décrite en référence à une batterie électrique 1 destinée à être fixée sur le plancher 2 d'un véhicule automobile, mais il est bien entendu qu'elle peut s'appliquer à la fixation sur ce plancher de tout autre équipement technique, tel que par exemple une boîte à outils ou un boîtier électronique. The invention will be described with reference to an electric battery 1 to be fixed on the floor 2 of a motor vehicle, but it is understood that it can be applied to the fixing on this floor of any other technical equipment, such as for example a toolbox or an electronic box.
[0021 ] Le plancher 2 comprend une traverse 3 fixée transversalement dans la direction longitudinale du véhicule entre deux longerons parallèles 4 du plancher 2. The floor 2 comprises a cross member 3 fixed transversely in the longitudinal direction of the vehicle between two parallel longitudinal members 4 of the floor 2.
[0022] De préférence, la traverse 3 est une traverse d'assise supportant l'assise d'un siège avant du conducteur ou du passager du véhicule et qui délimite un espace entre le dessous de l'assise du siège avant et le plancher 2 pour permettre le logement de la batterie électrique 1 dans cet espace situé vers l'avant du véhicule comme symbolisé par la flèche AV. [0023] Les doubles flèches X, Y et Z aux figures 4 et 6 symbolisent respectivement les directions longitudinale, transversale et verticale du véhicule. Preferably, the cross member 3 is a cross-member supporting the seat of a front seat of the driver or passenger of the vehicle and which delimits a space between the bottom of the seat of the front seat and the floor 2 to allow the housing of the electric battery 1 in this space located towards the front of the vehicle as symbolized by the arrow AV. The double arrows X, Y and Z in Figures 4 and 6 respectively symbolize the longitudinal, transverse and vertical directions of the vehicle.
[0024] La batterie électrique 1 peut être utilisée pour servir d'alimentation à divers appareils électriques ou électroniques, tels que par exemple des consoles de jeu et est dans le cas présent en forme générale de parallélépipède rectangle plat. The electric battery 1 can be used to power various electrical or electronic devices, such as for example game consoles and is in this case in the general shape of flat rectangular parallelepiped.
[0025] Selon l'invention, le dispositif de fixation de la batterie électrique 1 sur le plancher 2 du véhicule comprend une première série de dents externes espacées en forme de crochets 6 solidaires le long d'un premier côté 1 a de la batterie électrique 1 . According to the invention, the device for fixing the electric battery 1 on the floor 2 of the vehicle comprises a first series of outer teeth spaced in the form of hooks 6 integral along a first side 1a of the electric battery 1.
[0026] Ainsi, chaque dent en forme de crochet 6 comporte une dent rectiligne 6a s'étendant perpendiculairement au premier côté 1 a de la batterie électrique 1 et une extrémité en forme de crochet 6b s'étendant perpendiculairement à la partie rectiligne 6a en sens opposé au plancher 2 lorsque la batterie électrique 1 est disposée sur ce plancher. Thus, each hook-shaped tooth 6 comprises a rectilinear tooth 6a extending perpendicularly to the first side 1a of the electric battery 1 and a hook-shaped end 6b extending perpendicularly to the rectilinear part 6a in sense opposite the floor 2 when the electric battery 1 is disposed on this floor.
[0027] Les dents 6 sont régulièrement espacées le long du premier côté 1 a de la batterie électrique 1 et sont de préférence situées en partie inférieure de la batterie électrique 1 au niveau de sa base plane d'appui 1 b sur le plancher 2. Les dents 6 peuvent être réalisées en une seule pièce avec la batterie électrique 1 . The teeth 6 are regularly spaced along the first side 1a of the electric battery 1 and are preferably located in the lower part of the electric battery 1 at its flat base support 1b on the floor 2. The teeth 6 can be made in one piece with the electric battery 1.
[0028] Le dispositif de fixation comprend en outre une seconde série de dents externes espacées en forme de crochets 7 solidaires le long de la traverse 3 du plancher 2 en étant régulièrement espacées le long de cette traverse. The fixing device further comprises a second series of outer teeth spaced in the form of hooks 7 integral along the crosspiece 3 of the floor 2 being regularly spaced along the crosspiece.
[0029] Chaque dent en forme de crochets 7 comprend une partie rectiligne 7a s'étendant perpendiculairement d'une face verticale de la traverse 3 et une partie recourbée 7b s'étendant perpendiculairement de l'extrémité de la partie rectiligne 7a vers le plancher 2. Les dents en forme de crochets 7 de la traverse 3 sont régulièrement espacées le long de cette traverse de la même manière que les dents en forme de crochets 6 de la batterie électrique 1 . Each hook-shaped tooth 7 comprises a rectilinear portion 7a extending perpendicularly from a vertical face of the crosspiece 3 and a curved portion 7b extending perpendicularly from the end of the straight portion 7a to the floor 2 The hook-shaped teeth 7 of the cross-member 3 are regularly spaced along this cross-member in the same manner as the hook-shaped teeth 6 of the electric battery 1.
[0030] En outre, les dents en forme de crochets 7 de la traverse 3 ont leur parties rectilignes 7a qui s'étendent dans un même plan parallèle au plancher 2 et situées à un niveau supérieur au niveau des parties rectilignes 6a des dents en forme de crochets 6 de la batterie électrique 1 situées dans un même plan parallèle au plancher 2, lorsque la batterie 1 repose sur le plancher 2. Dans ces conditions, chaque dent en forme de crochet 7 de la traverse 3 peut être disposée au-dessus d'une dent correspondante 6 de la batterie électrique 1 de manière que leurs parties en forme de crochets 7a, 6a puissent s'imbriquer l'une dans l'autre comme cela est clairement représenté en figure 7 lorsque la batterie électrique 1 est fixée sur le plancher 2. [0031 ] Les dents en forme de crochets 7 sont formées sur une plaque qui est soit soudée sur la face verticale de la traverse 3 soit emboutie sur cette face. In addition, the hook-shaped teeth 7 of the cross member 3 have their straight portions 7a which extend in the same plane parallel to the floor 2 and located at a higher level at the rectilinear portions 6a of the shaped teeth. of hooks 6 of the electric battery 1 located in the same plane parallel to the floor 2, when the battery 1 rests on the floor 2. In these conditions, each tooth shaped hook 7 of the cross member 3 can be arranged above a corresponding tooth 6 of the electric battery 1 so that their hook-shaped portions 7a, 6a can interlock with one another as is clearly shown in Figure 7 when the electric battery 1 is fixed on the floor 2. The hook-shaped teeth 7 are formed on a plate which is either welded to the vertical face of the cross member 3 is stamped on this face.
[0032] Le dispositif de fixation comprend également une butée 8 solidaire d'une face verticale du longeron 4 adjacent au tunnel central, non représenté, s'étendant longitudinalement au véhicule, laquelle face verticale est celle se trouvant en regard d'un second côté 1 c de la batterie électrique 1 adjacent et perpendiculaire au côté 1 a de cette batterie comportant les dents en forme de crochets 6. The fixing device also comprises a stop 8 secured to a vertical face of the spar 4 adjacent to the central tunnel, not shown, extending longitudinally to the vehicle, which vertical face is that lying opposite a second side 1 c of the electric battery 1 adjacent and perpendicular to the side 1 a of this battery comprising the teeth in the form of hooks 6.
[0033] La butée 8 s'étend pratiquement tout le long de la partie d'extrémité du longeron 4 débordant vers l'avant du véhicule de la traverse 3 et peut être constituée par une plaque s'étendant perpendiculairement de la face verticale du longeron 4. [0034] Le dispositif de fixation comprend enfin une patte 9 de fixation de la batterie électrique 1 sur le plancher 2 et qui est solidaire d'un troisième côté 1 d de la batterie électrique 1 adjacent et perpendiculaire au côté 1 c de cette batterie, c'est-à-dire parallèle à son côté 1 a. The stop 8 extends substantially all along the end portion of the spar 4 projecting towards the front of the vehicle of the cross member 3 and may be constituted by a plate extending perpendicularly from the vertical face of the spar. 4. The fixing device finally comprises a lug 9 for fixing the electric battery 1 on the floor 2 and which is secured to a third side 1 d of the electric battery 1 adjacent and perpendicular to the side 1 c of this battery, that is parallel to its side 1 a.
[0035] La patte de fixation 9, qui s'étend parallèlement à la direction longitudinale X, comporte un trou oblong 9a qui s'étend suivant la direction transversale Y. The fastening lug 9, which extends parallel to the longitudinal direction X, has an oblong hole 9a which extends in the transverse direction Y.
[0036] En variante, la patte 9 peut être solidaire d'un quatrième côté 1 e de la batterie électrique parallèle au second côté 1 c. Alternatively, the tab 9 may be secured to a fourth side 1 e of the electric battery parallel to the second side 1 c.
[0037] La patte de fixation 9a peut être solidarisée au plancher 2 du véhicule par l'intermédiaire d'une vis de fixation 10 ancrée dans le plancher 2. La vis de fixation 10 peut être vissée dans un écrou 1 1 solidaire par soudage du plancher 2 ou peut tout simplement se visser dans un trou taraudé de ce plancher. The fixing lug 9a can be secured to the floor 2 of the vehicle by means of a fixing screw 10 anchored in the floor 2. The fixing screw 10 can be screwed into a nut 1 1 secured by welding the floor 2 or can simply screw into a tapped hole in this floor.
[0038] Tout comme les dents en forme de crochets 6 de la batterie électrique 1 , la patte de fixation 9 peut être située en partie inférieure de la batterie électrique 1 au niveau de sa base d'appui 1 b sur la plancher 2. [0039] Le procédé de fixation de la batterie électrique 1 sur le plancher 2 du véhicule ressort déjà de la description qui précède et va être maintenant expliqué. Like the hook-shaped teeth 6 of the electric battery 1, the fixing lug 9 may be located in the lower part of the electric battery 1 at its base 1b on the floor 2. The method of fixing the electric battery 1 on the floor 2 of the vehicle is already apparent from the foregoing description and will now be explained.
[0040] Un opérateur saisit la batterie électrique 1 pour la déposer sur le plancher 2 suivant une direction Z perpendiculaire à ce plancher de manière à disposer les dents en forme de crochets 6 de la première série de la batterie 1 respectivement entre les dents en forme de crochets 7 de la seconde série de la traverse 3 avec les parties rectilignes 7a des dents 7 situées dans un plan horizontal décalé au-dessus du plan horizontal contenant les parties rectilignes 6a des dents 6. La batterie électrique 1 se trouve ainsi à la position représentée en figure 4. [0041 ] Ensuite, l'opérateur déplace en translation la batterie électrique 1 en direction transversale Y vers le longeron 4 jusqu'à ce que le second côté 1 c de la batterie électrique 1 vienne en appui sur la butée 8 comme représenté en figure 5. A cette position, les extrémités recourbées 6b des dents en forme de crochets 6 de la première série de la batterie électrique 1 sont situées juste en dessous respectivement des parties rectilignes 7a des dents 7 de la seconde série de la traverse 3 et les extrémités recourbées 7b des dents 7 sont situées juste au-dessus des parties rectilignes 6a des dents 6 comme cela est représenté en figure 7. De la sorte, la batterie électrique 1 est bloquée en translation suivant les directions X et Z et en rotation autour des directions X, Y et Z. An operator grasps the electric battery 1 to deposit it on the floor 2 in a Z direction perpendicular to this floor so as to have the hook-shaped teeth 6 of the first series of the battery 1 respectively between the teeth in form hooks 7 of the second series of the crosspiece 3 with the straight portions 7a of the teeth 7 located in a horizontal plane offset above the horizontal plane containing the rectilinear portions 6a of the teeth 6. The electric battery 1 is thus in the position represented in FIG. 4. Next, the operator moves in translation the electric battery 1 in the transverse direction Y towards the spar 4 until the second side 1c of the electric battery 1 comes to bear on the stop 8 as shown in FIG. 5. In this position, the curved ends 6b of the hook-shaped teeth 6 of the first series of the electric battery 1 are situated just in under respectively rectilinear portions 7a of the teeth 7 of the second series of the cross member 3 and the curved ends 7b of the teeth 7 are located just above the straight portions 6a of the teeth 6 as shown in Figure 7. In this way, the electric battery 1 is locked in translation along the X and Z directions and in rotation around the X, Y and Z directions.
[0042] Ensuite, l'opérateur, à l'aide d'une visseuse, fixe la patte 10 au plancher 2 du véhicule par l'intermédiaire de la vis de fixation 10 ancrée dans l'écrou 1 1 du plancher 2 de manière à bloquer la batterie électrique 1 suivant la direction transversale Y. Then, the operator, using a screwdriver, fixes the lug 10 to the floor 2 of the vehicle by means of the fixing screw 10 anchored in the nut 1 1 of the floor 2 so as to block the electric battery 1 in the transverse direction Y.
[0043] En variante de réalisation, la butée 8 peut être omise, de sorte que la batterie électrique 1 pourra être déplacée en direction transversale Y vers le longeron 4 jusqu'à ce que le côté 1 c de cette batterie vienne en appui directement sur la face verticale du longeron 4 pour permettre ensuite la fixation de la batterie électrique 1 sur le plancher 2 par l'intermédiaire de la vis 10 à une position à laquelle les dents en forme de crochets 6 de la batterie électrique 1 et les dents en forme de crochets 7 de la traverse 3 soient imbriquées les unes au dessus des autres comme représenté en figure 7. As an alternative embodiment, the abutment 8 may be omitted, so that the electric battery 1 may be moved in the transverse direction Y to the spar 4 until the side 1 c of this battery comes directly on the vertical face of the spar 4 to then allow the attachment of the electric battery 1 on the floor 2 by means of the screw 10 to a position to which the hook-shaped teeth 6 of the electric battery 1 and the teeth shaped hooks 7 of the cross member 3 are nested one above the other as shown in FIG.
[0044] Il est à noter que le trou oblong 9a de la patte de fixation 9 permet un rattrapage de toute dispersion des cotes fonctionnelles. [0045] Selon la variante de réalisation représentée aux figures 8 et 9, le dispositif de fixation de la batterie électrique 1 sur le plancher 2 du véhicule ne diffère du dispositif de fixation décrit précédemment en référence aux figures 4 à 7 que par la présence d'un talon longitudinal 12 solidaire du second côté 1 c de la batterie 1 et qui s'étend perpendiculairement à la face verticale du côté 1 c vers le longeron 4 adjacent au tunnel central. It should be noted that the oblong hole 9a of the fixing lug 9 allows a catch of any dispersion of the functional dimensions. According to the embodiment shown in Figures 8 and 9, the device for fixing the electric battery 1 on the floor 2 of the vehicle differs from the fixing device described above with reference to Figures 4 to 7 that the presence of a longitudinal heel 12 secured to the second side 1c of the battery 1 and extending perpendicularly to the vertical face of the side 1c to the spar 4 adjacent to the central tunnel.
[0046] Le talon 12 peut venir en butée sur le longeron 4 en se logeant juste en dessous d'un rail ou glissière 13 pouvant être constitué par une plaque longitudinale fixée, par exemple par soudage, à la face verticale du longeron 4. [0047] L'installation et la fixation de la batterie électrique 1 sur le plancher 2 du véhicule s'opère en déposant la batterie 1 suivant la direction Z sur le plancher 2 de manière à engager les dents 6 de la batterie 1 respectivement entre les dents 7 de la traverse 3 comme représenté en figure 8. Ensuite, l'opérateur déplace en translation la batterie électrique 1 en direction transversale Y vers le longeron 4 jusqu'à ce que le talon 12 vienne en appui sur la face verticale du longeron 4 et en dessous du rail ou glissière 13 de ce longeron. Puis l'opérateur, à l'aide d'une visseuse, fixe la patte 9 au plancher 2 du véhicule par l'intermédiaire de la vis de fixation 10 ancrée dans l'écrou 1 1 du plancher 2. The heel 12 can abut on the spar 4 by being housed just below a rail or slide 13 which can be constituted by a longitudinal plate fixed, for example by welding, to the vertical face of the spar 4. [1] 0047] The installation and attachment of the electric battery 1 on the floor 2 of the vehicle takes place by depositing the battery 1 in the direction Z on the floor 2 so as to engage the teeth 6 of the battery 1 respectively between the teeth 7 of the cross member 3 as shown in FIG. 8. Next, the operator translates the electric battery 1 in the transverse direction Y towards the spar 4 until the heel 12 bears against the vertical face of the spar 4 and below the rail or slide 13 of this spar. Then the operator, using a screwdriver, fixes the lug 9 to the floor 2 of the vehicle through the fixing screw 10 anchored in the nut 1 1 of the floor 2.
[0048] Le talon 12 est situé de préférence en partie inférieure de la batterie électrique 1 et au niveau de sa base 1 b d'appui sur le plancher 2. [0049] Le dispositif de fixation ci-dessus décrit de l'invention dans ses variantes de réalisation résout le problème d'accessibilité des points de fixation P1 et P2 décrits dans l'art antérieur des figures 1 à 3 puisque seul le point de fixation P3 correspondant à la patte de fixation 9 et sa vis de fixation associée 10 sont utilisés pour fixer l'équipement au plancher 2 du véhicule en étant d'accès aisé pour l'opérateur, qui n'a plus à se pencher vers l'avant en bord de ligne de montage du véhicule comme dans l'art antérieur. En outre, le dispositif de fixation de l'invention réduit considérablement le temps de montage de l'équipement technique puisqu'il suffit de déposer verticalement l'équipement technique sur le plancher du véhicule et de le translater vers le longeron correspondant de ce plancher pour n'avoir à le fixer que par une seule vis de fixation, évitant tout problème de montage en aveugle d'un tel équipement. Le nombre de dents de l'équipement technique et de la traverse devant être imbriquées les unes dans les autres pour la fixation de cet équipement au plancher doit être déterminé pour assurer une tenue suffisante de l'équipement technique en cas de choc. L'ajustement des différents composants du dispositif de fixation de l'invention doit être tel qu'il permet la mise en place sans effort, notamment lors de la translation de l'équipement technique sur le plancher et sans risque de vibration par remontée de bruit dans l'habitacle du véhicule une fois l'équipement technique définitivement solidarisé au plancher du véhicule. The heel 12 is preferably located in the lower part of the electric battery 1 and at its base 1b of support on the floor 2. The above described fixing device of the invention in its variant embodiments solves the problem of accessibility of the fixing points P1 and P2 described in the prior art of FIGS. 1 to 3 since only the attachment point P3 corresponding to the fixing lug 9 and its associated fixing screw 10 are used to attach the equipment to the floor 2 of the vehicle being easy access for the operator, who no longer has to lean forward at the edge of the vehicle assembly line as in the prior art. In addition, the fixing device of the invention considerably reduces the assembly time of the technical equipment since it is sufficient to deposit the technical equipment vertically on the floor of the vehicle and translate it to the corresponding spar of the floor for only have to fix it by a single fixing screw, avoiding any problem of blind assembly of such equipment. The number of teeth of the technical equipment and the cross member to be nested in each other for the attachment of this equipment to the floor must be determined to ensure sufficient strength of the technical equipment in case of impact. The adjustment of the various components of the fixing device of the invention must be such that it allows the establishment effortlessly, especially during the translation of the technical equipment on the floor and without risk of vibration by rising noise in the passenger compartment of the vehicle a Once the technical equipment permanently attached to the floor of the vehicle.
