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. Indeed, it is too long to allow him to effectively lean on her when he is sitting 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 gets up and gives him help that 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 inner tube to be immobilized 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.
  • the present invention overcomes this drawback.
  • the telescopic stand described in US-A-4 245 659 comprises an upper part formed by a handle and a tube, a foot comprising at least one locking notch and slidably mounted in the tube between a retracted position and an extended position , securing means for securing in translation the tube and the foot in the retracted position thereof, these securing means can be moved between a first position in which they are engaged with the notch so that the foot is secured with the upper part of the stand, and a second position in which the notch is released from the securing means so that the foot can slide inside the tube, means for controlling the securing means, elastic means which urge the foot out of the tube, and stop means which prevent the foot from entering the tube from a partially or fully extended position.
  • the invention is characterized in that the handle is pivotally mounted relative to the tube, the securing means comprising a notch for receiving the notch, said handle being able to be moved by rotation between said first position and said second position, and means for locking in rotation of the handle in said second position being provided and being controlled by the control means.
  • 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 to urge said lug to exit the bore, an unlocking trigger being provided in the handle.
  • FIG. 1 is an overall view of a telescopic stand produced in accordance with the present invention
  • FIG. 2 is a view on an enlarged scale and partially in section of the lower part of the telescopic stand of the invention shown in FIG. 1.
  • 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 crutch of the invention shown in Figures 1 and 2 includes an upper part formed of 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 conventional type crutch.
  • 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 later.
  • the difference in diameter between the 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, which 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.
  • FIG. 3 and 4 There is shown in Figures 3 and 4 a particular embodiment of the means which allow the attachment of the leg 6 to the upper part of the stand, as well as a particular embodiment of the control means of these attachment 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 end of the handle 2.
  • a rod 24, terminated by a button 24a, is housed in the hole 22.
  • Its end 24b is capable of bearing on the pin 18 when the handle is suitably oriented. Indeed, this handle can be moved in rotation around the axis 12 by an angle to between a raised position, shown in Figure 3, and a lowered position, shown in Figure 4.
  • 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 leave 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.
  • the handle 2 has been shown in the unlocked position.
  • the rod 24 housed in the hole 22 is in contact with the end of the pin 18.
  • the helical spring 16 is relaxed.
  • the pin 18 engages in the hole 20 of the handle 2, so that a rotation of the latter relative to the axis 12, and therefore relative to the upper part 4 of the stand, is prohibited .
  • the projecting part 28 is in contact with a face of the recess 26 which forms a stop. This limits the rotational movement of the handle relative to the axis 12.
  • the notch 6c is released from the locking notch 32.
  • the rod 6b can therefore move inside the tube under the action of the helical spring 8, as shown schematically by the arrow 38.
  • the stand then takes the deployed position shown in Figures 1 and 2.
  • the trigger 10 engages in one of the holes 4a, which prevents the foot 6 from entering in the tube when you take support on the stand.
  • the tube 6 has several orifices 4a distributed over its length.
  • buttons 24a which makes the pin 18 penetrate the hole 14 provided in the axis by compressing the spring 16 until the end of the pin 18 is flush with the perimeter of the axis. It is then possible to move the handle 2 in rotation in the direction of the arrow 34 (FIG. 3).
  • 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 on the Figure 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 bc 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 makes it possible to pivot the handle 2 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.
  • the end 6a is then placed on the ground and the support is supported in one of the following ways:
  • the spring 8 is immediately released by bringing the handle 2 forwards in the direction of the arrow 36.
  • the action of the helical spring 8 can then be carried out but will only occur when the standing patient simultaneously relieves his or her weight. one crutch on the other.
  • the stand will reach its normal length in one or more stages depending on the number of holes 4a provided in the cane tube for the trigger 10.
  • 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 get inside the mechanism.
