Description

La présente invention industrielle a pour objet un chariot à roulettes destiné à l'usage des carreleurs, paveurs, parqueteurs et autres artisans analogues, comportant une plate-forme ayant une surface supérieure et une surface inférieure orientée vers le sol.The present industrial invention relates to a trolley with wheels for use by tilers, pavers, floorers and other similar craftsmen, having a platform having an upper surface and a lower surface facing the ground.

Il existe un certain nombre de métiers manuels pour lesquels les artisans se trouvent obligés de rester longtemps agenouillés pour réaliser leur travail, en particulier les carreleurs, paveurs, parqueteurs etc.There are a number of manual trades for which craftsmen are obliged to stay kneeling for a long time to do their work, especially tilers, pavers, floor artists, etc.

Lorsque l'on conserve une position agenouillée pendant longtemps, les genoux doivent supporter une charge considérable, ce qui provoque de graves pathologies permanentes telles que la bursite, l'arthrose et autres problèmes similaire souvent regroupés sous le terme générique de « maladies du carreleur ».When a kneeling position is maintained for a long time, the knees must bear a considerable load, which causes serious permanent conditions such as bursitis, osteoarthritis and other similar problems often grouped under the generic term "tiler's disease". .

Jusqu'à présent, une solution pour résoudre un tel problème consistait à faire enfiler des genouillères rembourrées aux artisans concernés, les genouillères utilisées étant du même type que celles utilisées par les joueurs de volley-ball.Until now, one solution to solve such a problem was to put padded knee pads to the artisans concerned, the knee pads used being of the same type as those used by volleyball players.

Chaque genouillère est constituée d'un manchon élastique d'une hauteur permettant de couvrir une grande partie de la jambe de l'utilisateur, du tibia jusqu'au-dessus du genou. La genouillère comporte sur la partie frontale qui protège le tibia une sorte de coussinet fermé contenant un rembourrage.Each knee brace consists of an elastic sleeve of a height to cover a large part of the user's leg, from the tibia to above the knee. The knee brace has on the front part that protects the shin a kind of closed cushion containing padding.

Naturellement, le manchon élastique d'une telle genouillère présente, en position de repos, une section étroite; ce n'est d'ailleurs que de cette manière qu'elle peut, une fois enfilée autour de la jambe de l'usager à hauteur du genou, parvenir à "étreindre" énergiquement cette jambe afin de maintenir fermement sa position visant à protéger le genou et le tibia de l'utilisateur.Naturally, the elastic sleeve of such a toggle has, in the rest position, a narrow section; it is only in this way that it can, once strung around the user's knee-high leg, succeed in "energetically" hugging that leg in order to firmly hold its position to protect the knee. knee and shin of the user.

Dans leur utilisation sportive susmentionnée, ces genouillères ne causent aucun problème étant donné que l'athlète qui les porte se tient debout.In their aforementioned sports use, these knee pads do not cause any problem since the athlete wearing them is standing.

Par contre, l'emploi de ces genouillères par des carreleurs paveurs et des parqueteurs n'est pas aussi efficace. En effet; ces derniers doivent effectivement se tenir longtemps avec les jambes en position pliée (ce qui correspond à se mettre à genoux) et ils finissent par ressentir, à l'arrière des genoux, une pression très forte provoquée par les parties postérieures des manchons élastiques.On the other hand, the use of these kneepads by tilers and pavers is not as effective. Indeed; these must actually stand long with the legs in the folded position (which corresponds to kneeling) and they end up feeling, at the back of the knees, a very strong pressure caused by the posterior parts of the elastic sleeves.

Très souvent, cette pression prolongée provoque des problèmes de circulation sanguine à la personne qui porte les genouillères et peut même causer des excoriations ou des blessures superficielles.Very often, this prolonged pressure causes blood circulation problems to the person wearing the knee pads and can even cause excoriations or superficial injuries.

Une autre solution connue du document US-A-5577800 est un chariot sur lequel l'utilisateur peut s'agenouiller.Another known solution of the document US Patent 5577800 is a cart on which the user can kneel.

Le but de la présente invention consiste à permettre aux personnes devant rester agenouillées de façon continue, à pouvoir le faire confortablement sans ressentir de douleurs et sans avoir de problèmes ultérieurs de santé dus au maintien prolongé de la position agenouillée.The object of the present invention is to allow people to remain kneeling continuously, to be able to do comfortably without feeling pain and without subsequent health problems due to prolonged maintenance of the kneeling position.

Pour cela, la présente invention prévoit selon les termes de la revendication 1 un chariot à roulettes destiné à l'usage des carreleurs paveurs, parqueteurs et autres artisans analogues comportant une plate-forme ayant une surface supérieure et une surface inférieure orientée vers le sol, dont les roulettes sont omnidirectionnelles (6) et qui sont fixées sur la surface inférieure de la plate-forme qui est de préférence polygonale et au centre de laquelle est fixé un siège (5) réglable en hauteur, la surface supérieure de ladite plate-forme (2) étant recouverte d'au moins une couche rembourrée qui a un profil incliné dont la partie la plus basse est située dans la partie située à l'avant du siège sur la surface supérieure de la plate-forme.For this purpose, the present invention provides according to the terms of claim 1 a trolley with wheels for the use of tilers pavers, floor and other similar craftsmen having a platform having an upper surface and a lower surface facing the ground, whose rollers are omnidirectional (6) and which are fixed on the lower surface of the platform which is preferably polygonal and in the center of which is fixed a seat (5) adjustable in height, the upper surface of said platform (2) being covered with at least one padded layer which has an inclined profile, the lowest part of which is situated in the part situated at the front of the seat on the upper surface of the platform.

Cette inclinaison particulière a été réalisée pour favoriser la posture naturelle prise par les parties inférieures d'une personne restant en position agenouillée.This particular inclination has been made to favor the natural posture taken by the lower parts of a person remaining in a kneeling position.

Dans cette position en effet, les points de contact entre le corps de l'utilisateur et la surface supérieure de la plate-forme du chariot se trouvent au niveau des genoux ainsi qu'au niveau des pointes des pieds.In this position, in fact, the points of contact between the body of the user and the upper surface of the carriage platform are at the knees and at the tips of the feet.

En tenant compte de la longueur des pieds, dans la position agenouillée sur le chariot de l'invention, les chevilles se trouvent à une distance du sol beaucoup plus grande que celle où se trouvent les genoux, de sorte que les parties inférieures susnommées des jambes ont une position inclinée du haut vers le bas, de la cheville au genou.Taking into account the length of the feet, in the kneeling position on the carriage of the invention, the ankles are at a much greater distance from the ground than the knees, so that the lower parts of the legs mentioned above have an inclined position from top to bottom, from ankle to knee.

Ainsi, le profil incliné de la couche rembourrée qui peut être par exemple un coussin, permet à l'utilisateur d'avoir une position sensiblement inclinée en appuyant toute la partie inférieure avant de ses jambes sur un support souple et substantiellement anatomique ce qui est très confortable et permet de travailler en diminuant beaucoup la fatigue occasionnée par la position agenouillée.Thus, the inclined profile of the padded layer which can be for example a cushion, allows the user to have a substantially inclined position by pressing the entire lower front of his legs on a flexible and substantially anatomical support which is very comfortable and can work by reducing much fatigue caused by the kneeling position.

Un avantage du chariot de la présente invention est que la plate-forme comporte deux bords latéraux de part et d'autre du siège, qui forment un rebord dont la hauteur est au moins égale à celle de la couche rembourrée. De cette façon, la surface inférieure de la plate-forme est très proche du sol, ce qui facilite le travail de l'utilisateur.An advantage of the carriage of the present invention is that the platform has two side edges on either side of the seat, which form a flange whose height is at least equal to that of the padded layer. In this way, the lower surface of the platform is very close to the ground, which facilitates the work of the user.

Un avantage supplémentaire du chariot de l'invention est qu'il est muni d'un siège de préférence de forme sensiblement triangulaire et présentant un relief prévu pour s'adapter à l'anatomie d'un utilisateur. Ainsi, l'utilisateur peut s'installer sur le siège, la point du triangle vers l'avant, de façon à disposer ses jambes repliées de part et d'autre de la pointe, son postérieur confortablement disposé sur les deux autres pointes du triangle qui ont de plus un relief parfaitement adapté.An additional advantage of the carriage of the invention is that it is provided with a seat preferably of substantially triangular shape and having a relief adapted to adapt to the anatomy of a user. Thus, the user can sit on the seat, the point of the triangle forward, so as to have his legs folded on either side of the tip, his posterior comfortably arranged on the other two points of the triangle which have a perfectly adapted relief.

D'une part, le poids résiduel du corps qui se décharge sur les jambes de l'usager (après soustraction du poids que celui-ci a déjà déchargé sur les fesses) ne se concentre plus uniquement sur les genoux, mais il est réparti, en s'allégeant ensuite sur toute la longueur des régions tibiales.On the one hand, the residual weight of the body that is discharged on the user's legs (after subtraction of the weight that the latter has already discharged on the buttocks) no longer focuses solely on the knees, but is distributed, then lightening the entire length of the tibial regions.

D'autre par, les genoux de l'utilisateur du chariot de l'invention ne sont plus en contact direct avec une surface rigide et froide (comme le sont normalement un pavement ou son fondement), mais sont en contact avec un coussin souple et confortable.On the other hand, the knees of the user of the carriage of the invention are no longer in direct contact with a rigid and cold surface (as are normally a pavement or its foundation), but are in contact with a flexible cushion and comfortable.

D'autres détails et particularités de l'invention ressortiront de la description donnée ci-après, à titre non limitatif et avec référence au dessin annexéOther details and particularities of the invention will emerge from the description given below, without limitation and with reference to the appended drawing.

La figure illustre une vue en perspective d'un mode de réalisation préféré d'un chariot selon l'invention.The figure illustrates a perspective view of a preferred embodiment of a carriage according to the invention.

Le chariot 1 de l'invention, sous sa forme préférée de réalisation, est constitué d'une plate-forme à plan carré 2 dont les bords latéraux 2a sont relevés de part et d'autre du siège 5 et sont repliés horizontalement vers l'extérieur de la plate-forme pour former deux tablettes 2b.The carriage 1 of the invention, in its preferred embodiment, consists of a platform with a square plan 2 whose lateral edges 2a are raised on both sides of the seat 5 and are folded horizontally towards the outside of the platform to form two tablets 2b.

La surface supérieure de la plate-forme 2 est recouverte par un coussin 3 ayant un profil incliné dont la partie la plus basse est située dans la partie située à l'avant du siège sur la surface supérieure de la plate-forme.The upper surface of the platform 2 is covered by a cushion 3 having an inclined profile whose lowest part is located in the part located at the front of the seat on the upper surface of the platform.

Au centre de cette plate-forme 2 s'élève également une courte tige 4 sur laquelle est fixé un siège confortable 5 dont il est possible de régler la position en hauteur.In the center of this platform 2 is also a short rod 4 on which is fixed a comfortable seat 5 whose height can be adjusted.

Sous les tablettes 2b sont fixée des roulettes appropriées, couplées et omnidirectionnelles 6 permettant au chariot 1 d'être facilement déplacé selon le bon vouloir de l'usager qui s'y est assis, sans que celui-ci ne doive jamais se lever.Under the shelves 2b are attached appropriate wheels, coupled and omnidirectional 6 allowing the carriage 1 to be easily moved at the pleasure of the user who sat there, without it must never get up.

A cet égard, il faut souligner que le choix consistant à avoir monté lesdites roulettes 6 en dessous des tablettes 2b du chariot 1 permet à la plate-forme 2 dudit chariot 1 d'être maintenue à une distance extrêmement proche du sol (au point de presque l'effleurer).In this regard, it should be noted that the choice of having mounted said wheels 6 below the shelves 2b of the carriage 1 allows the platform 2 of said carriage 1 to be maintained at a distance extremely close to the ground (at the point of almost touch it).

De cette manière, l'usager en position « assise - agenouillée » sur le chariot 1 se trouve dans une position de travail équivalent à celle typiquement adoptée par les carreleurs paveurs qui s'agenouillent directement sur le sol, sans en présenter aucun des inconvénients.In this way, the user in the "sitting-kneeling" position on the carriage 1 is in a working position equivalent to that typically adopted by tile tilers who kneel directly on the ground, without presenting any of the disadvantages.

Ainsi qu'il est illustré, la surface supérieure de la plate-forme 2 du chariot 1 est recouverte, par exemple d'un coussin dont la partie située à l'arrière du siège 5 a une épaisseur plus importante que celle de la partie du coussin située à l'avant du siège 5. De cette façon, l'appui des jambes se fait dans une position inclinée vers l'avant. Les chevilles de l'utilisateur s'appuient sur la partie postérieure plus épaisse du coussin, tandis que les genoux s'appuient sur la partie avant ayant une épaisseur moindre.As illustrated, the upper surface of the platform 2 of the carriage 1 is covered, for example with a cushion whose part located at the rear of the seat 5 has a greater thickness than that of the part of the cushion in the front of the seat 5. In this way, the support of the legs is in an inclined position forward. The user's ankles rest on the thicker posterior portion of the cushion, while the knees rest on the front portion having a smaller thickness.

Le but de cette disposition est en effet d'empêcher que les pointes des pieds de l'usager en position "assise-agenouillée" sur le chariot 1 de l'invention parviennent, dans leur position substantiellement verticale, à toucher le sol, ce qui gênerait l'utilisateur.The purpose of this provision is indeed to prevent the tips of the user's feet in the "sitting-kneeling" position on the carriage 1 of the invention reach, in their substantially vertical position, to touch the ground, which would annoy the user.

De même, il est possible d'éviter aux doigts de pied de l'utilisateur du chariot 1 de se trouver dans une position d'inflexion contrainte qui est loin d'être reposante et naturelle et qu'il devrait maintenir, sous le poids du corps tout entier, s'il devait se tenir agenouillé directement sur le sol.Similarly, it is possible to avoid the toes of the user of the carriage 1 to be in a position of inflection constraint that is far from relaxing and natural and it should maintain, under the weight of whole body, if he were to kneel directly on the ground.

L'utilisation du chariot 1 de l'invention permet à chaque utilisateur de régler la hauteur du siège 5 central afin de travailler dans la meilleure position en fonction de sa morphologie.The use of the carriage 1 of the invention allows each user to adjust the height of the central seat 5 to work in the best position according to its morphology.

La structure du chariot 1 de l'invention est prévue pour que l'utilisateur puisse modifier facilement sa position tout en restant assis sur le siège 5 du chariot 1.The structure of the carriage 1 of the invention is provided so that the user can easily change its position while sitting on the seat 5 of the carriage 1.

Par conséquent, étant donné qu'il peut conserver la position typique agenouillée du carreleur paveur, l'utilisateur peut également allonger ses jambes, afin d'utiliser ses pieds pour déterminer les déplacements du chariot 1 d'un point à l'autre du pavement, ce qui lui évite de devoir se lever et se remettre à genoux assez souvent comme devaient le faire les carreleurs jusqu'à aujourd'hui.Therefore, since it can retain the typical kneeling position of the tiler paver, the user can also extend his legs, in order to use his feet to determine the movements of the carriage 1 from one point to another pavement which saves her from having to get up and get back on her knees quite often, as the tilers had to do until today.
