Definitions

  • the invention relates to a forearm crutch, comprising a support tube with a contact surface on the underside, a handle that protrudes from the support tube in the direction of walking, and a forearm clamp or cuff arranged above the handle for guiding the forearm, the handle and the forearm clamp or cuff being closed integrated into a shaped upper part terminating the support tube at the top, and wherein the side of the shaped upper part facing away from the handle can serve as a contact surface when the forearm crutch is leaned against a wall or a piece of furniture.
  • a generic forearm crutch is in the utility model specification DE 20 2006 010 732 U1 disclosed. There the problem is addressed that such a crutch very often tends to fall over when parked.
  • This document therefore proposes providing the upper part of the crutch with a covering made of a material with good surface adhesion, with neoprene or cellular rubber being particularly recommended as the covering material.
  • a crutch can be leaned against a wall or other vertical surface, in which case only the upper edge of the crutch comes into contact with the wall or surface, especially in the area of a forearm clamp or - cuff.
  • the crutch can often only be leaned against the edge of a table or, at best, against the backrest of a chair.
  • the upper edge of the crutch does not come into contact with the edge of the table or chair back, but rather an area below the forearm clamp or cuff, and thus also below the two DE 193 08 044 A1 provided rubber knobs, so that they cannot prevent falling over in such a case.
  • the crutch usually has a cylindrical geometry and therefore tends to roll or slip sideways and thus ultimately to fall over.
  • ⁇ ⁇ 2 mm preferably ⁇ ⁇ 5 mm, or ⁇ ⁇ 10 mm, the horizontal distance between two edges laterally delimiting the contact surface gradually increasing from the height of the handle to the height of the forearm clamp or cuff enlarged.
  • the invention first defines a roll axis that runs on the one hand through the contact surface on the underside, for example through its center or through its rear edge area, and on the other hand through the center of gravity of the crutch.
  • This center of gravity can be determined experimentally, for example, by balancing the horizontally aligned support tube with the handle pointing downwards on an edge or cutting edge running transversely to it in order to find the height of the center of gravity along the longitudinal axis of the support tube, and on the other hand the horizontally aligned handle on the edge or cutting edge running transversely to the handle is balanced in such a way that the support tube assumes an upright position in order to determine the position of the center of gravity in the walking direction.
  • the actual center of gravity is then along the support tube at the previously determined height and in the direction of the walking direction approximately parallel handle by the previously determined amount in front of the support tube.
  • This forward displacement results from the fact that both the handle and the forearm clamp or cuff project forward at the upper end of the support tube, i.e. pull the center of gravity forward.
  • the invention has also recognized that precisely this position of the center of gravity in front of the support tube is responsible for the unstable position of a parked forearm crutch. This is due to the fact that when a crutch is parked, the roll axis defined in this way is inclined backwards, similar to the support tube, so that if the parked crutch tilts slightly to the side around its upper contact point in the area of the contact surface, the center of gravity also rolls to the side and as a result the inclination of the support tube reduces its height above the ground. This releases further energy, which in turn feeds the lateral rolling movement of the parked forearm crutch and thus leads to an unbraked, even accelerated continuation of the rolling movement. In the case of a generic forearm crutch, this movement is therefore not stopped until it has finally fallen over.
  • the invention now provides a special cross-sectional design of the plastic upper part in the area of the rear contact surface of a forearm crutch, namely in such a way that the radius r(h) is a maximum circle circumscribed around the cross-section, but which still has at least two points of contact with the cross-section of the contact surface has, is greater than the distance d(h) between the roll axis and the bearing surface at the height h.
  • a dimensioning means that if the crutch rolls or tilts sideways at height h, the distance between the roll axis on the one hand and the rear contact point or contact point increases. As a result, the center of gravity shifts upwards when the support tube is at a slight angle, which requires energy.
  • the crutch can be attached to a horizontal edge, e.g a chair or on the top edge of a dresser, etc., without the risk of it falling over.
  • the contact surface configured according to the invention extends along the entire height extension h of the back of an upper part that integrates the forearm clamp or cuff on the one hand and the handle on the other. This provides maximum security against accidental falling over.
  • the invention can be further developed such that the two lateral edges of the contact surface are mirror-symmetrical to a plane spanned by the longitudinal axis of the support tube on the one hand and the longitudinal axis of the handle on the other.
  • the contact surface can be designed mirror-symmetrically to a pointing in the direction of walking, vertical center plane, which contributes to the fact that the Focus of the crutch is in this center plane and a tendency to tilt sideways is minimal.
  • the horizontal distance between the two edges in the area of the handle can correspond approximately to the diameter of the pipe support there.
  • the horizontal distance between the two marginal edges gradually increases from the level of the handle to the level of the forearm band or cuff.
  • the further up a contact point is, the further the center of gravity of the forearm crutch is shifted away from this contact point in the horizontal direction, and the more unstable the respective position is.
  • the contact surface can be widened towards the top so that the stable area becomes larger.
  • the horizontal distance between the two marginal edges in the area of the forearm band or cuff should correspond to at least about half the width of the forearm band or cuff.
  • the curvature radii of the edges are 20 mm or smaller, for example 10 mm or smaller, preferably 5 mm or smaller, in particular 2 mm or smaller. These marginal edges may well be distinctive, as long as they do not pose a risk of injury. The smaller the radius of curvature in question, the wider the actual contact surface can be designed with the overall width of the arrangement otherwise being the same.
  • the invention permits a development in that the lateral edges are raised relative to the inner area of the contact surface are trained.
  • the contact surface can have a concave cross-section or even have a trough-shaped or even window-shaped depression.
  • the actual contact points are then in the area of the edge edges.
  • the contact surface can extend between the two edges without interruption.
  • This is a comparatively simple construction, the center of gravity of the forearm crutch being shifted backwards by the extension according to the invention, which acts as a counterweight to the handle, whereby the stability criterion according to the invention is improved.
  • the contact surface it is also possible for the contact surface to have at least one recess between the two edge edges. Weight can be saved by a recess, so that the forearm crutch becomes lighter overall.
  • the areas near the lateral edges of the contact surface are most valuable for the stability criterion according to the invention, because they are effective when the crutch is slightly rotated about an axis roughly parallel to the roll axis and finally form the actual axis of rotation and then decide on the stability of the position.
  • the area between these marginal edges on the other hand, is of secondary importance and can therefore be left out. At most, care should be taken to ensure that the recess is symmetrical to a center plane spanned by the handle and the support tube, in order to minimize the risk of a rolling moment when the forearm crutch is parked.
  • At least one such recess can be formed as a groove running in the vertical direction, which is flanked on both sides by two halves of the contact surface.
  • a maximum weight saving can be achieved with a recess in the form of a groove that completely divides the contact surface into two halves in the vertical direction.
  • the at least one recess is designed as a slot that is open at the top and is delimited by the contact surface at the bottom and on both sides.
  • the lateral marginal edges of the enlargement supporting the abutment surface diverge upwards, two remaining marginal regions converge downwards similar to an open-topped "V".
  • the at least one recess can be in the form of a trough-shaped depression which is surrounded on all sides by the contact surface like a frame. This also makes it possible, in particular, to connect the lateral edge regions to one another both at the bottom and at the top end, despite the weight saving, in order to achieve maximum stability.
  • a crutch according to the invention experiences a further improvement in stability in that the contact surface consists of a material with a rough surface structure. Then such a crutch can also be leaned against smooth surfaces, even if they are made of stainless steel, or exposed concrete, glass, tiles, natural stone, woodchip, wood or plastic or artistically designed, uneven ceramic tiles.
  • the contact surface can consist of a friction-increasing material such as an elastomer or be covered with such a material. Even a fabric covering or soft upholstery of the contact surface is conceivable, so that it can cling to the relevant wall or furniture edge.
  • the contact surface or in particular a widening of the plastic upper part that supports it, can be designed as a counterweight to the forward-pointing handle and/or can be provided with a counterweight thereto.
  • the center of gravity of the overall arrangement is shifted backwards against the walking direction and thus moves closer to a furniture edge or wall when the crutches are parked, which is beneficial to stability against the crutches falling over.
  • the invention further provides that the contact surface is formed integrally with the forearm crutch.
  • the contact surface can be designed together with the handle and a forearm clamp or cuff as a common plastic upper part. In such a case, it can be produced as part of a single injection molded part.
  • the contact surface is manufactured separately and connected or connectable to the crutches, for example by means of adhesive, a Velcro fastener, screws, etc.
  • Such a connection technique also allows conventional crutches to be retrofitted according to the present invention.
  • the contact surface is provided with a reflector, which is preferably directed backwards.
  • a reflector which is preferably directed backwards.
  • it can be better than integrating the reflector into the contact surface itself, to arrange it next to, below or above the actual contact surface, so that its stability against lateral slipping is not impaired.
  • the contact surface can be provided with a light source directed backwards, so that the crutch is clearly visible in the dark. Again, it may be advantageous not to integrate this light source directly into the contact surface, but to arrange it next to, above or below it.
