Definitions

  • the invention relates to a foot part forexcellentgeht. Crutch stick with a tubular socket and a support part articulated thereon by means of a ball joint, the ball part of the ball joint being guided in the axial direction against a compression spring on a correspondingly curved inner surface of a hollow cylindrical socket in the hollow cylindrical space of the socket.
  • Such a foot part is known from GB-A-1 373 593. It has a support part which is formed from two elements which can be displaced in relation to one another in the axial direction, of which one has a downward-facing sliding surface and the other has a downward-pointing gripping surface. At low loads, only the sliding surface is in contact with the ground, while at higher loads, e.g. when supporting a person, the gripping surface comes into contact with the ground.
  • the ball of the ball joint is supported on its side facing away from the support part against an abutment part, the support surface of which is adapted to the shape of the ball and which in turn is supported on the bottom of the hollow cylindrical interior of a tubular connecting piece via a plate spring.
  • crutch sticks are disadvantageous in that the support part maintains its relative position to the shaft of the stick after lifting off the floor, since no measures are provided to automatically move the support part back to a starting position in the unloaded state, in which the underside of the support part perpendicular to the axis of the shaft end is aligned.
  • the support part When the support part is placed on the floor again, it can slip or at least suddenly twist, which represents a considerable source of danger.
  • Such dangers should, however, be avoided by a foot part articulated to the shaft of the stick.
  • a disc spring to cushion the ball of the ball joint, only a small suspension stroke is available to absorb shocks that lead to fatigue and pain in the forearms of the affected user.
  • the invention has for its object to improve the foot part of the type mentioned in that the support member is automatically moved back to its original position in the unloaded state, in which its underside, which comes into engagement with the ground in use, substantially perpendicular to the axis of the shaft end is aligned, on which the foot part is arranged.
  • the foot part specified at the outset according to the invention in that the ball part of the ball joint is hemispherically aligned with a downward curvature and in that the compression spring is designed in the form of a coil spring as a return device, by means of which the support part can be automatically moved into its initial position in the unloaded state is.
  • a ball part 2 is fastened to the support part 1 by means of a screw 3.
  • the spherical part 2 has a hemispherical curvature 4 which is directed downwards.
  • the guide part 2 is guided in a hollow cylindrical bushing 5 so as to be displaceable in the axial direction.
  • the surface of the curvature slides on a correspondingly shaped surface on the inside of the socket 5.
  • the surface of the curvature 4 is pressed against this surface on the socket 5 by means of a compression spring 6, which is designed as a helical spring and is on the ball part 2 on the one hand and on the bottom of a cylindrical recess 7 of a connector 8 which can be placed on the shaft end of the walking or crutch stick.
  • the socket 5 is inserted into this recess 7.
  • a tension spring 9 ' is provided, which extends coaxially to the compression spring 6 and is fastened to the connecting piece 8 by means of a screw 9.
  • the spring force of the compression spring 6 is greater than that of the tension spring 9 ', so that the guide part 2 is pressed down.
  • the foot part thus has a support part which is articulated and guided in the manner of a ball joint and which yields with a certain force when it is placed on it. In this way, hard impacts are absorbed, which lead to the above-mentioned symptoms of fatigue and overload.
