Definitions

  • the invention relates to a non-slip body with a ball joint for the lower end of the stick of a walking aid, wherein the anti-slip body has a tread support and the hollow spherical shell of the ball joint is located in an axial central opening of a ring and from complementary partial spherical shell profiles at the upper end of the central opening and on the inner end face of a plug inserted from below into the central opening and the ball of the ball joint has a pin which protrudes from the upper end of the central opening of the ring and is connected to the stick.
  • the known anti-skid body is more complicated and expensive than such an important additional element for a walking aid for the disabled is appropriate.
  • Another major shortcoming of this anti-skid body is its considerable height, which makes it too large and bulky for a stick.
  • the tread carrier has a bore for receiving the pin of the ball and the ring forms a connecting part for connecting the anti-slip body to a stick.
  • the central opening of the ring is closed at the top by a spring-loaded plug.
  • the ball can be torn off the pin or at least cracks can result, which later lead to breakage.
  • access to the central opening is also free, through which dust, dirt and water penetrate into the hollow spherical shell, which can damage the ball joint and render it inoperable.
  • the object of the invention is to improve a non-slip body so that it has a ball joint that functions safely over a long period of use under all conceivable conditions and is characterized by a compact, robust design with a low height.
  • the anti-skid body has a ball joint that functions safely over a long period of use under all conceivable conditions and is characterized by a compact, robust design with a low height. Few parts that can be easily assembled are sufficient for the construction of the anti-skid body according to the invention, so that it can be inexpensively manufactured both in terms of material consumption and the production of parts and assembly.
  • the edge flange on the ring is advantageously overlapped by an inward edge part of the tread carrier. This results in a solid cohesion of the parts in use. For example, to replace the worn tread carrier, the parts can be easily separated from each other by lifting the snap-in grip.
  • edge flange is formed on the outer wall of a circumferential groove in the bottom of the ring and the opposite inner wall faces the groove and that an adapted profiled, Hollow approach engages the tread bracket, which has the edge part on the outer circumference.
  • the result is that the approach of the tread support serving as a connecting element is supported both on the inside by the inner wall and on the outside by the outer wall of the groove of the ring.
  • This bilateral support prevents shear forces that occur when the anti-skid z. B. is loaded with a lateral force when the user stands up, can tear off the highly stressed approach of the tread wearer.
  • the extension has a section set back to the outwardly directed edge part and the outer circumference of the edge part is smaller than the outer circumference of the tread support. Since the edge part is set back against the outer circumference of the tread support, the outer surfaces of the ring and the tread support plugged together with it can merge into one another without a step, i. H. have the same outside diameter.
  • the smoothness of the circumference of the anti-slip body is important so that it cannot get caught and cause the user of the walking aid to fall.
  • the transition between the edge part and the recessed section is advantageously stepped at right angles.
  • the edge part of the tread support and the recessed section have approximately the same height.
  • the profiling on the inner surface of the outer wall of the groove, which engages with the edge part of the attachment, is also dimensioned accordingly.
  • the outward edge portion and the recessed portion of the extension are advantageously provided with a cylindrical peripheral surface.
  • the outward-facing edge part of the attachment forms an inclined surface with the section set back to this.
  • the outer wall of the groove runs obliquely in line with the profiling of the outer circumference of the attachment and at its free edge a plurality of flat circumferential grooves are formed on the inner surface.
  • the matched inclined surfaces are easy to manufacture. Their cohesion is firm and offers a good connection between the ring and the tread support.
  • the inner wall of the groove is slightly bevelled downwards and inwards and that the inner wall of the hollow extension is cylindrical. This beveling of the groove in connection with the cylindrical wall surface of the attachment results in an increased pressing of the attachment material, which brings about an improvement in the cohesion of the parts.
  • the narrowed end opposite the closed end of the central opening of the ring is covered with an outer curved ring sleeve, the thickness of which decreases from the inside to the outside.
  • a stick connecting piece 2 is suitably inserted, which consists of a sleeve which rests with an end flange 3 against the edge of the stick 1, so that it cannot slip into it.
  • a longitudinal opening 4 of the sleeve of the pole connector 2 is part of a shaft designed as a cylindrical pin 5, which is integrally formed on a ball 6 made of metal or plastic.
  • an annular collar 7 is arranged on the pin 5, which is embedded in an annular extension 8 at the lower end of the opening 4 of the pole connector 2.
  • the pin 5 protrudes through the narrowed end 9 of the central opening 10 of a ring 11, which can also be made of metal or plastic.
  • the inner surface of the central opening 10 is adapted in the region of the narrowed end 9 as a profiled spherical shell profile 12 of the ball 6.
  • the axial continuation of this profile 12 of the central opening 10 is equipped with an internal thread 13 which extends to the end of the central opening 10.
  • the diameter of the central opening 10 of the ring 11 is slightly larger at the narrowed end 9 than the collar 7 of the pin 5, so that it can be inserted through the ring 11.
  • a plug 15 is inserted into the central opening 10 from below, and is screwed to the internal thread 13 by means of an external thread 16.
  • the plug 15 is preferably made of self-lubricating material and has a concave partial spherical shell profile 17 on the surface facing the narrowed end 9 of the central opening 10, the radius of curvature of which corresponds essentially to that of the ball 6.
  • the lower surface of the plug 15 screwed into the central opening 10 is flush with the lower surface of the ring 11 (FIG. 2) and the plug is secured against unscrewing by means of a grub screw 18.
  • a cap-shaped tread support 19 engages over an edge flange 21 of the ring 11 with an inward edge 10 and forms together with the ring 11 the anti-skid body with a smooth cylindrical outer surface, which is articulated to the stick 1 via the ball 6.
  • a lubrication opening 22 in the bottom of the plug 15 enables the ball 6 to be lubricated if the plug 15 is not made of self-lubricating material.
  • a stick connecting piece 102 is suitably inserted, which consists of a sleeve which bears with an end flange 103 against the edge of the stick 101, so that she cannot slip into it.
  • a longitudinal opening 64 of the sleeve of the stick connector 102 is part of a cylindrical pin 105 which is integrally formed on a ball 106 made of metal, preferably brass.
  • an annular collar 107 is arranged on the pin 105, which is embedded in an annular extension 108 at the lower end of the opening 104 of the pole connection piece 102.
  • the pin 5 protrudes through the narrowed end 109 of the central opening 110 of a ring 111, which can be made of harder plastic.
  • the inner surface 112 of the central opening 110 is adapted to a belt zone of the ball 106 at the narrowed end 109.
  • the axial continuation of this inner surface 112 of the central opening 110 is provided with an internal thread 113 which extends to the end of the central opening 110.
  • the diameter of the narrowed end 109 of the central opening 110 of the ring 111 is slightly larger than the collar 107 of the pin 105, so that it can be inserted through this narrowed end.
  • a plug 115 is inserted into the central opening 110 from below and is screwed to the internal thread 113 by means of an external thread 116.
  • the plug 115 is preferably made of self-lubricating material and has a concave spherical shell curvature 117 on the surface facing the narrowed end 109 of the central opening 110, the curvature radius of which essentially corresponds to that of the ball 116.
  • the lower surface of the plug 115 screwed into the central opening 110 is flush with the bottom of the ring 111 (FIG. 4), and the plug 115 is secured against unscrewing by means of a welding point 140.
  • a circumferential groove 131 is formed in the bottom of the ring 111, which is open at the bottom and is delimited by an outer wall 132 and an inner wall 133.
  • the inner wall 133 is slightly beveled from top to bottom and inside, while the inner surface of the outer wall 132 is stepped cylindrical. It assigns one of the in Neren wall 133 facing edge flange 134 which protrudes at right angles from the inner surface of the outer wall 132.
  • the groove 131 serves to receive a profiled axial extension 135 of a tread support 130.
  • the extension 135 has a smaller outer diameter than the body 136 of the tread support 130. It consists of an outwardly directed edge part 137 and a section 138 set back to this.
  • the edge part 137 and section 138 are of substantially the same height. Their dimensions are adapted to the profile of the outer wall 132 of the groove 131.
  • the inclined surface of the inner wall 133 of the groove slightly compresses the cylindrical inner wall 139 of the hollow lug 135, resulting in an improvement in the engagement between the connection profiles 134 and 137. Since the outer diameter of the section 138 of the projection 135 is smaller than the outer circumference of the body 136 of the tread support, the outer circumference of the body 136 and the ring 111 can be dimensioned the same, so that there is a continuous peripheral surface of the entire anti-skid body.
  • the tread 148 of the tread support 130 has two relatively deep U-shaped grooves 141 which intersect at right angles and which openly end on the circumference of the tread support 130 (FIG. 5). Between these four rows of four ring segment ribs 142 are provided.
  • the grooves 141 are sharp-edged; they prevent aquaplaning and improve the anti-slip effect of the anti-slip body.
  • a ball 206 is inserted into the central opening of a ring 252 and is held in position by a screwed plug 215 secured by a welding point 240.
  • the ball 206 is surrounded by a sealing ring 214 in the area of its largest circumference. It has a pin 205, the annular collar 207 of which is embedded in an extension of a sleeve 202, into the longitudinal opening 204 of which the pin 205 projects.
  • At the lower end of the sleeve 202 there is an end flange 203, against which the edge of a stick 201 lies flush.
  • the connecting elements between a tread support 249 and the ring 252 here consist of an outer inclined surface 245 of a shoulder 253 of the tread support 249 and an adapted inclined surface 244 in the outer wall of the groove 254 of the ring 252.
  • the inclined surface 245 extends from the top outside inward below.
  • the inner wall 246 of the projection 253 is cylindrical, while the inner wall 247 of the groove 254 is directed obliquely downwards and inwards.
  • the interaction of the wedge 244 and the counter wedge 245 and the surfaces 246, 247 results in the solid cohesion of the parts 249 and 252.
  • the tread 248 of the body 251 of the tread carrier 249 is profiled in a similar way to the tread 148 of the body 136 of the example according to FIG. 3 to 5 and provided with ring segment ribs 242.
  • a ring sleeve 243 made of rubber-elastic material. It is wedge-shaped in cross-section with flattening increasing towards its outer edge.
  • the ring collar 243 moves with the pin 205 and practically completely prevents the ingress of dirt, etc. into the ball housing.
  • the ring collar 207 prevents them from slipping upward on the pin 205.
  • the ring sleeve 243 can also be used in the anti-skid bodies according to FIGS. 1 to 4.
