Definitions

  • the invention relates to a non-slip body with a tread support, which is fastened to a base body, which is connected to the lower end of the stick of a walking aid via a ball joint, the hollow spherical shell of which is located in the axial central opening of a ring and of complementary partial spherical shell profiles on one End of the central opening and on the end face of a plug inserted into the other end of the central opening and fastened therein and the ball has a shaft which protrudes from the curved end of the central opening of the ring and is fastened in a bore of a connecting piece.
  • the ball In a known anti-skid body with ball joint (DE-PS 341 874), the ball consists of two hemispherical shell parts which are urged in opposite directions by a spring. A shaft rises from the cavity of one shell part, which extends through an opening in the other shell part and is connected to the base body.
  • the hollow sphere Shell for receiving the ball is formed at one end of a sleeve and separated by a constriction from a cylindrical part of the sleeve which is attached to the stick.
  • a major disadvantage of this construction is that when a vertically downward pressure is exerted on the stick, its lower end moves downwards relative to the ball, so that the constriction of the sleeve is pushed apart by the ball and the ball moves into the sleeve can move up. As a result, the ball loses its tight fit in the hollow spherical shell and is no longer securely stored in the expanded hollow spherical shell. Such a loosening of the ball in their pan is very dangerous for the user of the stick, because the coherent connection between the stick and the anti-slip body is suddenly broken and the only loose connection between these parts can lead to an oblique deflection of the stick, which leads to the user Case brings.
  • the ball With such an oblique deflection of the stick, the ball can also be torn off the shaft or at least cracks can result, which later lead to breakage. It is also disadvantageous that the lifting of the ball in the hollow spherical shell opens access to its interior, through which dust, dirt and water can penetrate into the hollow spherical shell, by which the function of the ball joint is impaired, if not prevented. Dust and dirt roughen the surfaces of the ball and the hollow spherical shell over the course of time and reduce their lubricity, and the water completely damages or blocks the ball joint when it is frozen.
  • the anti-slip body is not particularly robust due to its construction from deformable half-shells and its screwing to the carrier parts, and it is the assembly of the anti-slip body as well its connection with the stick and the base body complicated and expensive. Disassembly of the anti-skid body, for example for cleaning or replacing parts, is not possible in a simple manner. Due to its design, the anti-slip body becomes unreasonably expensive for the application.
  • the base body connected to the tread support has the bore for receiving the shaft of a one-piece ball, and the ring supporting the ball forms the connecting part for connecting the anti-skid body to a stick.
  • the ball thus protrudes upward from the anti-slip body and a stopper, a Belville spring ring, a stopper and a rib serve to support it in the central opening of the ring.
  • the tread carrier connected to the base body consists of two parts which are movable relative to one another, one part serving as a slider and normally protruding with its sliding surface over the flat anti-slip surface of a brake piece.
  • the invention has for its object to design a non-slip body so that it is robust and its ball joint connection with the walking aid stick reliably withstands all forces occurring in practice for a long time It should be inexpensive to manufacture by simple construction, be easy to assemble or disassemble and have a compact design.
  • This object is achieved in that the connecting piece receiving the shaft of the ball is connected to the stick, and in that the base body is formed from the ring, in the central opening of which the plug is inserted from below and with its flat lower surface flush with the lower surface of the ring runs against which the tread carrier attached to the ring is attached.
  • the result is a non-slip body, the ball of which is directed downward and is mounted in a pan supported against the floor. How strongly the stick is loaded and at what angle it runs with respect to the anti-slip body, no force is able to loosen the ball in the rigid hollow spherical shell formed from the ring and stopper.
  • the ball is housed dust-tight in the capsule which firmly encloses it and is protected against the ingress of liquid. Even after a long period of use, the ball joint works perfectly without unwanted play.
  • the assembly of the anti-skid body is easy both in its manufacture and after disassembly for maintenance or for the replacement of parts.
  • the anti-slip body is assembled and connected to a stick via the ball joint.
  • the anti-slip body is inexpensive to manufacture due to its construction from a few robust, simple parts and its uncomplicated assembly. Its height is low so that it does not interfere with a walking stick or a crutch.
  • the plug is screwed into the central opening of the ring and secured against unscrewing. This further simplifies the assembly and disassembly of the anti-skid body.
  • the plug screwed into the central opening of the ring allows the ball seat to be re-tensioned to compensate for wear or to adapt to the wishes of the user.
  • a groove is advantageously formed in the central opening of the ring, in which there is a rubber-elastic sealing ring which touches the circumference of the ball.
  • At least the plug can be made of self-lubricating material.
  • an axial lubrication opening can be formed in the middle of the partial spherical shell profile of the stopper.
  • An annular collar is provided on the shaft in the vicinity of the ball at a slight distance from it, which forms a stop in the connecting piece and which has a smaller diameter than the narrowed end of the central opening of the ring.
  • the ring collar determines the insertion depth of the shaft in the connection piece and, in conjunction with the diameter of the opening of the narrowed edge of the ring, defines the angular range of the relative movement between the anti-slip body and the stick.
  • An edge flange is formed on the ring, which is overlapped by an inward edge of the cap-shaped 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.
  • an edge flange is formed on the outer wall of a circumferential groove in the bottom of the ring which faces the opposite inner wall of the groove and that in the groove on Profiled, hollow approach of the tread wearer engages with 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 body e.g. when the user gets up is subjected to a lateral force that can tear off the highly stressed connecting elements of the tread wearer.
  • the extension has an outwardly directed edge part and a section set back to it, and the outer circumference of the edge part is smaller than the outer circumference of the tread carrier. Since the edge part is set back against the outer circumference of the tread support, it is possible that the ring and the tread support can have the same outer diameter and the outer surfaces of the ring and the tread support plugged together with it merge seamlessly into one another. 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 step-like right-angled.
  • the edge part of the tread support and the recessed section have approximately the same height.
  • the profile on the inner surface of the outer wall of the groove, which engages with the shoulder profile, 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 hollow extension comes to rest against the inner wall of the groove of the ring, which is slightly slanted downwards and inwards. This bevel in connection with the cylindrical wall surface results in an increased compression of the attachment material, which improves the cohesion of the parts.
  • Deep grooves which intersect at right angles and have sharp edges and ends which are open towards the peripheral edge of the tread support, are formed in the lower surface of the tread support, between which there are several rows of ring segment ribs. This tread pattern improves the slip resistance of the anti-skid body because it offers protection against aquaplaning.
  • 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 partial spherical shell profile 12 of the ball 6.
  • the axial continuation of this profile 12 of the central opening 10 is provided with an internal thread 13 which extends to the end of the central opening 10.
  • On the boundary between the p r of i - 12-regulation and the internal thread 13 is a rubber elastic sealing ring 14 which is inserted into a groove.
  • 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 essentially corresponds 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 inwardly directed edge 20 and together with the ring 11 forms the anti-slip 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 fitting 102 is fitted, which consists of a sleeve which abuts 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 pole 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 is that of Ball 106 essentially corresponds.
  • 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 11'5 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 has an edge flange 134 facing the inner wall 133, which projects at a right angle 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 outside 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-slip 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 manner to the tread 148 of the body 136 of the example according to FIGS. 3 to 5 .
  • a ring sleeve 243 made of rubber-elastic material. It is wedge-shaped in cross-section with a 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.
