Definitions

  • the present invention relates to a crutch, and more specifically to a crutch as disclosed in the preamble of independent claim 1.
  • a crutch with a shoulder support and a spring-mounted hand support is previously known from US-Al 5901724. Apart from the spring-mounted hand support, this crutch differs little from crutches of the type that have been known from way back and which are, inter alia, known from old war films.
  • a crutch for simultaneous support of the user's hand and forearm is previously known from DE 195 47 484 Al, the said publication describing a crutch where the hand grip at one end is rigidly connected to the forearm support and at its other end is rigidly connected to the rod-shaped part of the crutch by means of a continuous tube.
  • the crutch according to the present invention endeavours to provide an improvement of the previously known crutches for a more natural gait and better support of the user's body when using the crutch.
  • the crutch according to the invention is characterised by the features disclosed in the characterising clause of independent claim 1.
  • Figure 1 is a perspective partial view of the crutch according to the invention.
  • Figure 2 is a schematic diagram of the crutch shown in Figure 1 in different positions while in use.
  • FIG. 1 is a partial view of a crutch 50 according to an advantageous embodiment of the invention, which crutch includes a rod 1, a handgrip 3 connected to the upper end of the rod 1, and a forearm support 5, and wherein an armpit support 7 is pivotally mounted to the forearm support 5.
  • the pivot point 9 of the armpit support 7 is advantageously adjustable essentially in the vertical direction by means of a first adjustment device 11 arranged between the pivot point 9 of the armpit support 7 and the forearm support 5.
  • a second adjustment device 13 is advantageously arranged between the pivot point 9 and the armpit support 7 for essentially vertical adjustment of the distance between the armpit support 5 and the pivot point 9.
  • the first and the second adjustment devices 11, 13 make it possible to adjust the pivot point 9 to lie level with the elbow joint of a user.
  • the first adjustment device 11 is advantageously an adjustment bracket attached to the back of the forearm support 5.
  • the second adjustment device 13 is advantageously an adjustable rod or telescopic connection.
  • the pivoting of the armpit support link 9 is advantageously limited by a stop 17 to an essentially extended state of the crutch 50, essentially only forward swinging of the rod 1 relative to the armpit support 7 being allowed, as shown in Figure 2.
  • a stop 17 In the position marked 1. in Figure 2 the load on handgrip 3, forearm support 5 and armpit support 7 is further indicated by respective arrows.
  • the armpit support 7 and/or forearm support 5 are advantageously padded.
