Definitions

  • the invention relates to a telescopic stand for the physically disabled and more specifically for paraplegics.
  • a cane or crutch of the conventional type that is to say one whose foot has a constant length suitable for walking, does not allow its user to get up easily. In fact, it is too long to allow Him to effectively lean on it when it is seated and preparing to get up.
  • Document FR-A-2 526 281 describes a telescopic rod of variable length which attempts to remedy this drawback. It lengthens as the patient stands up and gives him help which can be effective.
  • US-A-4 245 659 (SHOFNER) a stand whose length can be adjusted according to the needs of the user. It comprises a transverse element adapted to be fixed to the patient and a pair of crutches mounted on the transverse element by means of ball joints. Each stand includes a pair of telescopic cylindrical tubes.
  • the inner tube has undulations which allow it to be immobilized relative to the outer tube.
  • a spring housed inside the inner tube urges it out of the outer tube.
  • An oblong element which has ribs on the side opposite the handle allows the immobilization of the inner tube in a fully or partially extended position. These ribs are intended to engage in the undulations of the inner tube.
  • a control rod housed in the handle allows the user to unlock and lock the oblong element using the hand holding the handle.
  • iL is difficult for a paraplegic to use his fingers to press a button or lever while he is resting on his crutches; It can happen that it can unlock one of the springs and not the other, or that it can unlock both springs, but not exactly at the same time, which would cause it to fall.
  • the present invention overcomes this drawback.
  • the telescopic stand of the invention comprises an upper part formed by a handle and a tube, a foot comprising at least one locking notch and mounted sliding in the tube between a retracted position and an extended position, securing means to secure in translation
  • the tube and the foot in the retracted position of the latter can be moved between a first posi tion in LaqueLLe they are engaged with the notch in such a way that the foot is secured to the upper part of the stand, and a second position in LaqueLLe the notch is released from the stop means so that the foot can slide at L inside the tube, means for controlling the securing means, elastic means which urge the foot to exit the tube, stop means which prevent the foot from entering the tube from a partially or fully extended position .
  • the handle is pivotally mounted relative to the tube, the foot having a notch for receiving the notch, said handle being able to be moved by rotation between said first position and said second position, means for rotating the handle in said second position and means for controlling the locking means being provided.
  • the means for controlling the locking means consist of an axis linked in rotation to the tube, a bore being formed in said axis, a hole being located opposite the bore of the axis in the first position of the handle, a locking lug being displaceable in translation in the bore, elastic means being provided for urging said lug to come out of the bore, an unlocking trigger being provided in the handle.
  • Figures 3 to 5 are sectional views which show preferred embodiments of the means for securing the foot with the stand and the control of these securing means;
  • Figure 3 shows the stand in the locked position and Figure 4 in the unlocked position;
  • FIG. 5 is a variant of FIGS. 1 to 4.
  • the stand of the invention shown in FIGS. 1 and 2 comprises an upper part formed by a handle 2 and a tube 4.
  • the handle comprises the handle 2a proper as well as The cuff 2b intended to serve as a support for the patient's forearm, as in a crutch of the conventional type.
  • the handle 2 could be constituted by a simple knob.
  • the foot 6 has a rubberized lower end 6a intended to increase the grip with the ground and an upper end 6b constituted by a rod of smaller section than the main part of the foot.
  • the rod has at its end a notch 6c whose function will be explained below.
  • the difference in diameter between Part 6b and The body of the foot determines a shoulder.
  • This shoulder serves as a support for one end of a helical spring 8, LequeL is housed in the tube 4.
  • the tube 4 has several openings 4a intended to stop a trigger 10 which is pushed into the extended position, as shown in FIG. 2 by an interior spring not shown, to prevent the foot 6 from penetrating inside the tube 4.
  • FIGS 3 and 4 There is shown in Figures 3 and 4 a particular embodiment of the means which allow the attachment of the foot 6 to the upper part of the stand, as well as a particular embodiment of the means for controlling these securing or locking means.
  • the handle 2 is pivotally mounted on the tube 4 around an axis 12 visible externally in Figure 1 and in section in Figures 3 and 4.
  • a hole 14 is made in the axis 12.
  • a spring 16 and a pin 18 are housed in the hole 14.
  • the handle 2 has a hole 20 whose diameter is substantially equal to that of the hole 14 and a hole 22 of smaller diameter, the hole 22 being coaxial with the hole 20 in which it opens at one of its ends. At its other end, it opens at the extreme part of the handle 2.
  • the angular movement of the handle by relative to the tube 4 is limited by a clearance 26 provided in the axis 12 and a portion 28 projecting from the handle 2 and engaging in the clearance 26 in order to limit the angular displacement thereof.
  • the handle 2 also has a recess 30 which has a locking notch 32 adapted to cooperate with the notch 6c of the foot 6. In FIG. 3, the notch 6c has been shown engaged inside the locking notch 32. In this position, the foot 6 cannot exit the tube 4 under the action of the helical spring 8 because the latter is retained at its upper part by the notch 6c.
  • the handle 2 can be moved to the locking position in the direction of the arrow 34 and to the unlocking position in the direction of the arrow 36.
  • this stand is as follows. From the deployed position shown in Figure 1, we move to the retracted position by manually erasing the trigger 10 so as to be able to penetrate the foot 6 in the tube 4. We also place the handle 2 in the position shown in FIG. 4, that is to say in such a way that the clearance 30 is presented opposite the notch 6c, the locking notch being in the released position. The foot 6 is pushed all the way inside the tube until this notch 6c is opposite the locking notch 32, as shown in FIG. 4. Then the unlocking button 24a is pressed to penetrate the pin 18 into the hole 14, as explained above. This allows the handle 2 to pivot towards the locking position in the direction of the arrow 34. The locking notch 32 enters the notch 6c. The stand is then in the folded position and the foot 6 can no longer leave the tube 4.
  • FIG. 5 an alternative embodiment of the device shown in Figures 1 to 4.
  • the contact surface between the upper part 4 of the stand and the handle 2 is not oriented upwards.
  • rainwater or dust for example, can get inside the mechanism, which can lead to its seizure or deterioration .
  • the rainwater is driven downwards by gravity without being able to enter the interior of the mechanism.
