Definitions

  • the invention relates to a walker device, intended more particularly but not exclusively for people with mobility difficulties such as persons with reduced mobility.
  • the invention has been developed to help people move.
  • Freezing is characterized by a sudden immobility that can last for a few seconds or a few minutes. The feet remain stuck to the ground, the person stomps and is unable to transfer the weight of his body on one leg in order to move forward. This syndrome is the cause of many falls.
  • Such a walker device can be bulky when not in use: that is why a foldable version is provided in this document.
  • the frame is designed in two parts connected together by a hinge.
  • the document US D 753 553 also presents a technical solution that allows the walker device to bend for less space when not in use.
  • the invention aims to provide a less bulky walker device when folded.
  • the invention also aims to provide a walker device that can easily be taken in hand, and that makes a plane support accessible to a user: in fact, the devices of the state of the art do not allow a user to to be able to access, in a comfortable way, a flat support, for example at a table, for cooking, for lunch, for playing.
  • this embodiment makes it possible to fold up the walker device when it is not in use, it does not allow the user to access a plane support in a comfortable way: indeed, when the user is on the device walker, the front part of frame abuts against a flat support whose height is lower than the height of the handlebars. Thus, when the user is on this walker device, the latter keeps the user away from the plane support.
  • Another embodiment of a walker device described in the document is known CN 202620130 .
  • This device is not a tricycle, but it comprises a yoke fixed on the main transom at a distance from said handlebar, between said first end of the transom and said seating device, so that said first end of the transom equipped with said handlebar forms with a front part of the frame an open angle towards the front of the walker device

  • the figure 25 further illustrates an alternative embodiment, according to which the device according to the invention comprises a saddle 15 whose height can be controlled manually:
  • the saddle 15 comprises a jack device, which can be actuated by means of a manual control system 58 fixed on the handlebar 5 and connected to the jack device via a cable system 59.
  • the saddle 15 rises under the action of the jack.
  • the user stops operating the manual control system and the saddle locks in position.
  • the user can also sit on the saddle while operating the manual control system 58: the saddle then drops under the pressure of the weight of the user.
  • the saddle can also descend by exerting a manual pressure on it.
  • This embodiment allows a patient to be easily positioned on the device without having to step over the saddle 15: thus, the user is positioned above the saddle through the back of the device. To do this, he pulls the camera to him to pass in his legs.
  • the brake system Before adjusting the seat height, the brake system must be actuated.
  • a particular saddle 15 which prevents the user having to spread his legs to position his crotch above the saddle 15.
  • the saddle 15 shown in figure 26 comprises three parts: a central saddle portion 150 and two saddle side portions 151.
  • the saddle side portions 151 are made symmetrical on both sides of the saddle central portion 150.
  • the central part of saddle 150 is fixed: it does not move vertically.
  • the vertical adjustment of the central part of the saddle is done either manually or thanks to the manual control system 58 mentioned above.
  • the two saddle side portions 151 are pivotally mounted between a retracted position shown in FIG. figure 27 and an unfolded position shown in figure 29 .
  • the figure 28 shows a semi-extended position of the lateral parts 151.
  • the saddle central portion 150 and the saddle side portions 151 are made of fleece for greater comfort of the user.
  • the saddle central portion 150 is fixed on a vertical axis 152.
  • the saddle side portions 151 are pivotally mounted about a point 153 fixed on the vertical axis 152.
  • the pivot is controlled by a pantograph 154, that is to say a device articulated on the vertical axis 152.
  • the pantograph 154 comprises, for this purpose, a pin 155, movably mounted along the axis 152, which is connected to the two lateral parts 151 by connecting rods 156.
  • the connecting rods 156 are symmetrical and each have a substantially bent shape: one end of the rods 156 is attached to a saddle side portion 151 and the other end is fixed to the pin 155.
  • the pin 155 is movably mounted between two high and low positions: in the high position of the pin 155 on the vertical axis 152, the saddle side portions 151 are in the extended position ( figure 29 ), and in the lower part of the pin 155 on the vertical axis 152, the saddle side portions 151 are in the retracted position ( figure 27 ).
  • It may be, for example, a clamp system.
