Definitions

  • the invention relates to a holder for interchangeable sole bodies on auxiliary means, according to the preamble of patent claim 1.
  • Brackets for interchangeable sole bodies on support feet of auxiliary materials are known (cf. prospectus Jolo-Renttol ", published by Joser Lottner, Cologne), in which the sole body is placed over the lower end of the support foot like a cap.
  • the invention has for its object to provide a holder according to the preamble of claim 1, which allows a quick and very convenient replacement of the sole body and works reliably over long periods of time.
  • the snap lock can be operated with minimal effort and can be released in the shortest possible time without the need for any tools.
  • the sole body can therefore be replaced with minimal effort.
  • the ease of use also largely prevents the disabled from getting dirty when replacing the sole body, so that the replacement process becomes even more convenient.
  • the snap lock can be designed and designed according to the special requirements placed on it, regardless of the design and nature of the sole body the replacement processes are only used to a negligibly small extent.
  • the area of the snap lock can thus be optimized with regard to the greatest possible wear resistance and operational reliability, but at the same time also the area of the sole body with regard to optimal power transmission from the ground to the walking aid independently of the other area.
  • the snap lock when the support leg is connected to the protective tube of the walking aid via a ball joint, the snap lock can be designed to be particularly simple in terms of construction, since in this case it does not have to absorb any moments, but only exactly defined and limited tensile forces in the axial direction. The operating reliability and the lifespan of the snap lock can be increased additionally.
  • the holder is equally advantageous both for fastening a sole body designed as a reversing body, and for a sole body which has a tread that protrudes in the manner of a plate on the bottom.
  • the holder according to the invention is thus universally applicable in that the socket rim serves as a universal fitting surface for various plate-like sole bodies and for an annular sleeve that is open on both sides for axially securing a reversible sole body, which is made of rubber-plastic and, for example, with a stud profile on the one side and on the other with Spikes is provided.
  • the plate-like sole bodies are generally made of a material that has a sufficiently high strength so that the union sleeve can be integrally formed on the sole body.
  • the holder according to subclaim 5 can be operated very easily with the thumb and forefinger, the positive engagement of the locking surface sections with the respective undercut axial slots of the union sleeve being completely eliminated, so that the union sleeve can be pulled off the rim without resistance.
  • the undercut axial slots are easy to manufacture because they run into the upper edge of the union sleeve.
  • the snap pins can be provided with relatively large pin heads without impairing the snap lock, through which the operability of the releasable snap lock is additionally improved. Because the connection between the coupling sleeve and the socket rim can only be released by pressing or pressing two snap pins at the same time can, the functional reliability of the bracket is further increased.
  • the guide in the support foot can be given a simple geometric shape.
  • the cylindrical locking and unlocking surface sections contribute to the undercut axial slots being easier to slide past the snap pins.
  • the cylindrical surface sections of the snap pins thus gradually bring the undercut axial slots into exact axial alignment with the snap pins.
  • the development according to subclaim 7 secures the snap pins on the one hand against falling out and assigns them to a precisely defined locking position regardless of the position of the other snap pin. Because the forces acting on the cap sleeve act in a direction that is perpendicular to the direction of movement of the snap pins, the compression spring biasing the snap pins can be made very weak, which makes the operation of the holder even more convenient.
  • the pin protruding into the diametral bore reliably fulfills the stop function with the simplest design.
  • Such a pin can, for example, be inserted into the support foot in a direction parallel to the axis of the coupling sleeve and can cooperate with a screwing in of the snap pins in the guide surface section.
  • the pin head is fitted with a fit in a recess of the union sleeve and covers the undercut axial slot, the risk of contamination of the snap lock is considerably reduced, so that the functional reliability of the holder can be further increased.
  • the sinking of the pin heads which can be achieved in a simple manner, precludes unintentional striking of the pin heads on an object; Even when the support leg sinks into snow or mud or the like, no external pressure force can act on the snap pins.
  • This development has the additional advantage that no dirt can penetrate from the outside to the functional surface sections of the snap pins.
  • Fig. 1 shows a crutch
  • the support tube 2 carries a support foot 3 to which an interchangeable sole body 4 is attached.
  • the sole body 4 is formed, for example, by a rubber-elastic block which projects to a certain extent from the underside of a support foot plate, which is connected to the support tube 2 either rigidly or via an articulated connection, for example via a ball joint.
  • an elastic bellows 5 extends from the support tube 2 to the support foot 3 in order to shield the joint connection from the surroundings.
  • the structure of the support foot 3 is shown in detail in Figures 2 to 5.
  • a spherical cap 7 is incorporated, which is in functional engagement with a ball pin, not shown, which is received with a clamp fit in the support tube 2 of the crutch 1.
  • the elastic bellows 5 extends from the outer surface of the support body 6 to the ball pivot and, on the one hand, shields the ball joint surfaces from the outside and, on the other hand, returns the smooth-running ball joint to its neutral central position.
  • the support body 6 is essentially in the form of a plate which has a socket edge B of height H 8 projecting from the bottom.
  • the rim 8 is essentially ring-shaped in order to be able to receive a sole body 4 under lateral guidance.
  • the rim 8 can be formed by a continuous ring.
  • the clarified embodiment shows a frame edge which is interrupted at two diametrically opposite points by plane-parallel surfaces 9.
  • the flat surfaces 9 extend up to a radial collar 10, the function of which will be explained in more detail below.
  • the outer surface 11 of the frame edge B serves as a clearance fit surface for a union sleeve 12 which can be pushed on from below and which fixes the sole body 4 both in the lateral direction and in the axial direction of the support foot 3.
  • the position is fixed in the lateral direction by suitable adaptation of the inner surface to the boundary surface of the sole body 4, which in the embodiment shown is designed as a rubber-elastic reversible sole body.
  • the plane-parallel surfaces of the reversible sole body are provided on one side with a profiling 41 and on the other side with steel pins 43 which are embedded or vulcanized into the rubber-elastic block.
  • the reversible sole body is shown with a dash-dotted line and has a radial collar 42 which is aligned with the end face of the rim 8, the lower or bottom collar surface of which is in contact with an inwardly drawn radial shoulder 13 of the coupling sleeve 12.
  • the radial shoulder 13 secures the sole body 4 against axial pulling off when the coupling sleeve 12 is fastened to the frame edge or to the support body 6.
  • the union sleeve 12 is fastened to the support body 6 by means of a snap connection 14 which can be released from the outside and which will be described in more detail below.
  • the snap connection consists of snap pins 15 and snap recesses in the coupling sleeve 12.
  • the snap pins 15 are received in a bore 16 running diametrically through the support body 6 and are supported on one another via a compression spring 17 which engages, for example, in a cylindrical recess 18 of the snap pins 15 .
  • the compression spring 17 By means of the compression spring 17, the snap pins 15 are pressed radially outward into a locking position shown in FIGS. 2 and 3, which is fixed by a stop body.
  • the stop body is formed by a pin 19 which protrudes into the diametral bore 16 and is in contact with a radial shoulder 21 of a recess 20 of the snap pin 15 in the locked position of the snap pins.
  • the pins 19 are pressed from below into the support surface of the support body 6, the heads of the pins 19 being sunk in the support body 6.
  • the snap pins 15 have a plurality of functional sections which are staggered in the axial direction: with respect to the support leg axis radially inward there are a guide section 151, followed by a recess 20, followed by a cylindrical locking surface section 152 in the embodiment shown, followed by a cone section 153 which merges into an unlocking surface section 154, to which a pin head 155 connects.
  • the locking surface section 152 protrudes from the flat surface 9 of the support body 6 by a dimension V.
  • the snap pin 15 By pressing the pin head 155, the snap pin 15 can be pushed into the diametral bore 16 against the force of the compression spring 17 to such an extent that the locking surface section 152 and the conical surface 153 come to lie within the support body 6. In the unlocked position of the snap pins 15, the unlocking surface sections 154 thus come to lie in the immediate vicinity of the flat surfaces 9.
  • the coupling sleeve 12 In adaptation to the design of the snap pins 15, the coupling sleeve 12, the inner surface of which is in circumferential contact with the socket edge 8, also has diametrically opposite locations on flat surfaces 22, which are in leading functional engagement when the coupling sleeve 12 is pushed on with the flat surfaces 9 of the supporting body 6.
  • Has 22 in the area of these plane surfaces the cap sleeve 12 therefore a material accumulation 23, the thickness S of which is large enough so that the pin heads 155 come to lie radially within the circumferential surface of the cap sleeve 12 in the locking position of the snap pins 15.
  • the outer surfaces of the pin heads 155 suitably end flush with the cylindrical surface of the union sleeve 12.
  • the sleeve 12 is formed symmetrically to a plane 24, which coincides with the central plane of the diametral bore 16 in the support body 6 in the pushed-on state of the coupling sleeve 12.
  • a plane 24 which coincides with the central plane of the diametral bore 16 in the support body 6 in the pushed-on state of the coupling sleeve 12.
  • undercut axial grooves 26 are formed or incorporated symmetrically to the plane 24, which are geometrically matched to the design of the snap pins 15.
  • the undercut axial slot 26 has a radial extent T which is approximately one third of the thickness S and essentially of the dimension V, but above all is not greater than the axial extent E of the unlocking surface section 154.
  • the axial slot 26 is adjoined radially on the outside Recess 27 in which the respective pin head 155 is received in a form-fitting manner.
  • the recess 27 has a stop shoulder 28 against which the inner surface of the pin head 155 can be pressed to unlock the snap connection 14.
  • the undercut axial slot 26 has an undercut surface 29, which is formed by a partial cylinder jacket surface, which can receive the locking surface section 152 of the snap pin 15 in a form-fitting manner.
  • the undercut surface 29 ends on the upper side at a narrow point 30 formed by two edges, the width W of which is somewhat larger than the thickness or the diameter of the unlocking surface section 154 of the associated snap pin 15.
  • the axial slot 26 widens slightly from the constriction 30 to the upper edge 25 of the coupling sleeve 12 in order to make the snap-in pins 15 snap into the axial slots 26 more easily.
  • the undercut axial slots 26 have the area in which the axial slot extends from the constriction 30 to the upper one Edge 25 slightly widened, radially inward wedge-shaped bevels 31, which are visible in FIGS. 2 and 5. These chamfers 31 come into contact with the conical surfaces 153 of the snap pins 15 and push them into the diametral bore 16 so far that the unlocking surface sections 154 can slide through the constriction 30 of the axial slot 26 when the sleeve 12 is pushed onto the rim B of the socket.
  • the pins 15 snap outwards under the action of the compression spring 17 and engage positively with the locking surface sections 152 in the undercut 29.
  • the undercut surfaces 29 cooperate with the locking surface sections 15Z in the locking position in such a way that the coupling sleeve 12 is stretched elastically upwards in the locked position.
  • This can be done, for example, when attaching a rubber-elastic reversing body 4 (as shown) in that the axis of the undercut 29 can only be brought into alignment with the central axis of the diametral bore 16 when the radial collar 42 of the reversing body 4 extends from the inwardly facing annular shoulder 13 of the sleeve 12 has been deformed by a certain and small amount in the axial direction.
  • the turning body 4 is supported on the supporting body 6 both via its radial collar 42 and via its flat surface facing away from the floor.
  • the support can also be provided via the steel pins 43, in which case, however, care should be taken to ensure that these pins do not press into the flat support surface 61 of the support body 6.
  • the holder is suitable not only for the detachable fastening of interchangeable cylindrical sole bodies, but in particular also for securing plate-like protruding support bodies, such as are used in a particularly advantageous manner when the disabled wants to move on very flexible ground.
  • the union sleeve is firmly connected to the sole body or is integrally formed thereon and is otherwise formed in the same manner as described above.
  • the introduction of the support force from the sole body into the support body 6 can take place via the top edge 25 and the radial shoulder 10 of the support body 6 and / or via the end face of the frame edge 8.
  • the coupling sleeve 12 can in this case be guided relatively far down, so that the sole body only protrudes a few mm from the radial shoulder 13.
  • the support foot can then be reliably placed on the entire surface of the sole body due to the ball joint if the coupling sleeve 12 only has a small face 32 at the lower end.
  • Either aluminum or dimensionally stable plastic such as, for example, can be used as the material for the union sleeve and for the snap pins 15.
  • HDPE plastic can be used.
  • the support foot remains very light, so that the disabled does not tire too quickly even on long walks, even with a plate-shaped and large-area sole body.
  • the axial pins 19 preferably come into contact with the other radial shoulder of the recess 20, so that in this case there is also a defined position of the snap pins which can be maintained without applying force to the coupling sleeve.
  • the union sleeve 12 'shown in FIGS. 7 to 9 differs from the one described above essentially by a flange section which extends from a bottom end face 122' of the union sleeve 12 ', projecting essentially in a radial plane to the outside.
  • the flange 121 ' is preferably formed by a pure or exact radial flange which is integrally formed on the cylindrical body of the union sleeve 12', which is preferably made of plastic.
  • the radial flange 121 'does not protrude beyond the end face 122' in the axial direction.
  • the outer diameter of the radial flange 121 ' essentially corresponds to 2 to 4 times the diameter of the sole body 4 to be accommodated within the coupling sleeve 12', which e.g. can be designed as a reversing body, as described in detail with reference to FIG. 2.
  • Such a support foot enables the handicapped to stand on firm and possibly very smooth, as well as on extremely resilient surfaces, such as move safely on the beach or in boggy terrain or snow without the need to change the sole; Because on solid ground only the sole body 4 bears, which in its design as a reversible body can be optimally adapted to the prevailing terrain and weather conditions, either by its spiked tread, its non-slip end face provided for normal ground or a wet cell tread Underground is facing. The sole body can still be turned over or even exchanged in the simplest way, since nothing changes in the easy accessibility of the sole body fastening means.
  • connection between the radial flange and the union sleeve, as well as the snap connection, are largely protected in this way, the latter in particular being largely unloaded when the union sleeve 12 ', which extends over its inwardly facing annular shoulder 13' and the radial collar 42 of the reversing body 4 on Supporting the rim 8 of the support body 6, exclusively or additionally when a certain elastic deformation distance of the sole body 4 has been overcome, can be supported with its top face 129 'on a radial collar 10 of the support body 6.
  • the ball joint also makes it possible to additionally increase the diameter of the radial flange without having to accept the disadvantage that any uncertainty when putting the walking aid on could occur when walking on a very smooth and hard surface.
  • the radial flange or plate 121 ' which is held at a predetermined distance V A when the sole body 4 comes into contact with one another, does not impair the safety of the walking aid against being placed on, even if it is made of very smooth and hard plastic and the crutch, for example on parquet or smooth stone floor. Because the relatively small angle of inclination of a maximum of 16 to 18 ° mentioned above exerts such a large tilting moment on the circumferential edge of the radial flange 121 'which is relatively radially outward that even with the smallest forces that the possibly existing restoring force of the ball joint, e.g. the elastic shielding bellows 5 is provided, is overcome immediately, ie before the actual support force is introduced, and the support foot can be brought into flat contact with the ground via the non-slip sole body 4.
  • the underside of the radial flange 121' has a surface design which increases the adhesive force, for example in the form of a profile 123 ' , which also takes on the task of fixing the support leg laterally when walking in very soft terrain.
  • the profiling shown in FIGS. 7 to 9 has a plurality of concentric ring webs 126 'and some recesses 127' running in the radial direction.
  • a coating 124 ' see FIG.
  • friction force increasing inserts 125 ' which are indicated by dash-dotted lines in FIG. 8, can be attached to the radial flange 121' e.g. be releasably attached.
  • the weight of the cap sleeve 12 ' is subjected to forces that are precisely defined and controllable in terms of size and direction throughout the entire course of the movement of the action, the weight of the cap sleeve can be kept relatively small, so that the disabled person does not tire even after a long walk with the multi-range support foot.
  • the radial flange 121 ' can additionally be provided with openings 128', without the operational reliability of the walking aid being influenced when walking in very flexible terrain.
  • the load conditions of the radial flange are so favorable that it does not necessarily have to form an integral part of the coupling sleeve 12 '.
  • the radial flange could also be attached to a correspondingly modified union sleeve 12 in a different manner, however, in a manner that prevents it from being pulled off.
  • the openings 128 'in the radial flange or support plate 121' additionally increase the support stability in soft and flexible terrain.
  • the radial flange 121 does not come to lie exactly in a radial plane. Rather, geometric shape deviations are quite possible without having to accept compromises in terms of the advantages described above.
