Definitions

  • the invention relates to a swimming shoe for learning or to support the leg beat for swimming in the breast, according to the preamble of claim 1 and a manufacturing process for the swimming shoe, according to claim 18.
  • Such swimming shoes are for example from the documents DE 26 58 584 A1 and DE 10 2007 003 508 B3 known. They are used as swimming and learning aids, on the one hand to make it easier to learn to swim and on the other hand to practice correct breast swimming techniques and also to continuously check them.
  • document WO2010 / 123345 A1 describes a breaststroke swimming shoe and a modular system.
  • the Hinge-like hinge device itself in this known case formed by two textile bands, of which one textile band on the inside of the joint on the sole of the shoe body and the top of the sole flap and the other textile band on the outside of the joint on a flap nose and on the side surface of the shoe body is arranged.
  • the textile tapes are attached to the respective sections with a high-strength adhesive, for example.
  • this known swimming shoe has manually operated fixer devices with which the sole flap is kept essentially parallel to the bottom surface of the shoe body when walking outside the swimming pool. This makes the construction of the swimming shoe a little more complex.
  • the invention is therefore based on the object of developing a generic swimming shoe in such a way that it ensures a long-term function with great ease of use with a simplified structure.
  • an elastic and outwardly bent flap is used in the joint arrangement, via which the sole flap is connected to the shoe body, the flap elastically pressing the sole flap with a prestress on a bottom surface of the shoe body.
  • the elastic flap stores energy in the form of prestressing force, which is used to pivot the sole flap back onto the shoe body. If the tab presses the sole flap on the bottom surface of the shoe body, there is the advantage that walking with the swimming shoe outside of the water is made easier.
  • the elastic flap prevents the sole flap from accidentally deflecting or swiveling out.
  • the sole flap always rests against the bottom surface of the shoe body without water resistance with sufficient pretensioning of the flap.
  • the dimensions of the tab can be varied within wide limits. This enables a robust Structure of the swimming shoe according to the invention, whereby the function is guaranteed over a long time.
  • the subject matter of claim 2 provides the advantage that the entire length of the tab can be used to provide the joint function.
  • the pivotable section pivots together with the sole flap through the water resistance, and then presses the sole flap with pretension against the bottom surface of the shoe body. With such a simple construction, the pivoting of the sole flap is made possible, the dimension of the tab being able to influence the prestressing force.
  • the pivot angle is limited by the stop of the sole flap or the tongue on the shoe body, but not by the elastic limit of the tongue. This has the advantage that the tab does not reach its elastic limit and thus the life of the tab is extended.
  • the tab with the shoe body can be produced as one part. This reduces the manufacturing effort and the cost.
  • the tab is separately attached to the shoe body.
  • the tab can e.g. be formed by a reinforced and possibly more expensive material to provide a safe function, while the shoe body can be formed by a non-reinforced material that is optimized for comfort and therefore generally less expensive. This enables economical production.
  • the pivoting section can be divided into several fastening tongues, which can be assigned different functions. This results in a further increase in the flexibility of the design.
  • the structure of the sole flap is simplified.
  • the connection is stabilized by braiding the fastening tongues of the tab into the sole flap.
  • the advantage of the development of claim 9 is that the pretensioning tongue provides a further supporting force which acts on the sole flap, it being possible to dispense with fastening the pretensioning tongue to the sole flap.
  • the sole flap can be mounted and replaced with the tab.
  • a plurality of ribs is formed on an underside of the sole flap, has the advantage that the sole flap is prevented from changing its shape when deflected and swung out.
  • the ribs can be given an anti-slip function.
  • the ribs extend in the transverse direction of the shoe body. With such a direction of extension of the ribs, the sole flap obtains its required stiffness to support the leg kick, while it does not hinder a rolling movement of the swimming shoe when running. User security is therefore improved.
  • the tab does not necessarily have to be formed with the same wall thickness everywhere.
  • a rib extending along the pivot axis may be formed at the position between the pivotable portion and the non-pivotable portion. This point can therefore become thicker if the tab is in a bent state. Therefore this point is reinforced by the rib. As a result, the long-term functionality is improved.
  • the swimming shoe can be economically manufactured, for example by injection molding. Because only one injection mold is required for a pair of swimming shoes for the two shoe bodies, right shoe body and left shoe body.
  • the manufacturing process according to claim 18 enables economical manufacturing. Because the flap is made integrally with the shoe body on the one hand by injection molding, and for a pair of swimming shoes it is only an injection mold for the two shoe bodies, the right and left Shoe body, required. This leads to economical production. On the other hand, if the tongue and the shoe body are manufactured separately by injection molding, they can be formed by different materials. Also in this manufacturing process, only one shoe body, a single flap and - for the second embodiment with the braided fastening tongues - a single sole flap are required, which can be used for the two shoes, the left shoe and the right shoe. This leads to a further simplification of the production.
  • reference numeral 10 designates a swimming shoe, more precisely the right swimming shoe, for learning or to support the contribution to breaststroke swimming.
  • a description of the left swimming shoe is omitted here, since it is mirrored to the right swimming shoe.
  • the swimming shoe 10 mainly consists of two parts, namely the actual shoe body 12 and a sole flap 14 connected to it via a joint arrangement 18, which will be described in more detail below in the Figures 6 and 7 is shown separately.
  • the hinge arrangement 18 has an elastic flap 20, via which the sole flap 14 is connected to the shoe body 12, the flap 20, by virtue of its flexurally elastic deformation, pressing the sole flap 14 elastically with a prestress on a bottom surface 32 of the shoe body 12.
  • the elastic flap 20 builds up a pretension with further flexurally elastic deformation, which is used to pivot the sole flap 14 back onto the shoe body 12.
  • the tab 20 is injection molded integrally with the shoe body 12, i.e. molded onto the shoe body.
  • the shoe body 12 with the flap 20 is formed from a thermoplastic elastomer, preferably a thermoplastic elastomer based on urethane (TPU).
  • TPU thermoplastic elastomer based on urethane
  • the sole flap 14 is designed as a plastic injection molded part.
  • Figure 5 shows the elastic tab 20 in a relaxed state, for example in the form in which it comes out of the injection mold together with the shoe body.
  • the sole flap is not yet installed.
  • the tab is still unprocessed.
  • part of the elastic tab 20 projects beyond the bottom surface 32 of the shoe body 12.
  • the portion of the tab 20 projecting beyond the base surface is bent outwards in the assembled state of the sole flap and connected to the sole flap 14.
  • the tab 20 builds up a prestressing force, via which the sole flap 14 is pressed elastically against the bottom surface 32 of the shoe body 12.
  • This protruding section of the tab 20 forms a pivotable section 30 which, together with the sole flap 14, can pivot due to water resistance when the leg is hit.
  • the section which does not project beyond the bottom surface 32 forms a non-pivotable or non-pivotable section 28 which is connected to the shoe body 12.
  • a pivot axis 16 of the joint arrangement 18 lies between the pivotable section 30 and the non-pivotable section 28.
  • the entire length of the bracket can thus be used to provide the joint function.
  • the tab 20 in the form of a material flap has a uniform wall thickness and - depending on the material - a thickness d in the range from 3 mm to 5 mm. Tests can show that long-term function can be guaranteed.
  • the tab does not necessarily have to be formed with the same wall thickness everywhere.
  • a reinforcing rib 60 can be formed between the pivotable section 30 and the non-pivotable section 28, which extends along the pivot axis 16 (this variant is shown in FIG Figure 5 indicated by dashed lines).
  • Figure 2 shows a bottom view of the swimming shoe 10 according to the first embodiment.
  • the sole flap 14 has an outer section 22, to which the pivotable section 30 of the tab 20 is fastened, and an inner section 24, which rests against the bottom surface 32 of the shoe body 12 in the retired state.
  • the sections 22 and 24 are separated from one another by the pivot axis 16.
  • the sole flap 14 has - as best from the Figures 6 and 7 can be seen - a bridge 26 projecting upward from the sole flap 14, which includes a first end section 34, a second end section 36 and a base plate 38, as a result of which a slot 40 is formed between the bridge 26 and the outer section 22 into which the pivotable section 30 the tab 20 can be inserted as a fastening tongue 42, as in FIG Figures 3 and 4 shown.
  • the fastening tongue 42 is inserted into the slot 40 from the inside.
  • the outer contour of the fastening tongue 42 thus follows the contour of the slot 40.
  • the fastening tongue 42 and thus the tab 20 can be detachably connected to the sole flap 14.
  • there are three drilled openings or bores 58 on the base plate 38 of the bridge 26 of the sole flap 14 three drilled openings or Bores 61 are formed on the outer portion 22 of the sole flap 14 and three drilled openings or bores 59 are formed on an end portion 43 of the fastening tongue 42 of the tab 20, each of which is flush with one another and into which a pin or a bolt can be inserted.
  • the openings 58, 59, 61 are matched to one another in terms of their position such that - as in Fig. 3 shown - the sole flap 14 lies flat on the bottom surface 32.
  • the three connection points are formed essentially along the longitudinal direction of the swimming shoe 10.
  • the tab 20 is thus positioned by the bridge 26 and connected to the sole flap 14 in a sandwich-like arrangement.
  • FIG 3 shows the state of the swimming shoe 10 with the mounted sole flap 14. It can be seen that the sole flap 14 is pressed flat against the bottom surface 32 of the shoe body 12 with the pre-tensioned portion 30 of the flap 20 which is bent outwards by approximately 90 °.
  • the sole flap 14 can also protrude slightly beyond the bottom surface contour on the side opposite the joint arrangement. If the leg beat is performed correctly, the sole flap will open due to the water resistance. As long as the water pressure is higher than the biasing force of the tab 20, the water is forced into the space between the sole flap 14 and the bottom surface 32 of the swimming shoe 10, whereby the sole flap 14 is pressed by 90 ° due to the water resistance and an upper side 27 of the bridge 26 the side wall of the shoe body 12 strikes.
  • the sole flap 14 which can be pivoted almost without resistance closes due to the flow resistance and the pretensioning of the flap 20, while the water from the space between the sole flap 14 and the bottom surface 32 the swimming shoe 12 is pushed. During the subsequent circular swing movement until the legs are extended, the sole flap 14 is opened again. Thus, the swimmer feels very quickly whether his foot position is right or wrong.
  • the sole flap 14 also has a plurality of ribs 44. These ribs 44 are formed on the underside 47 of the sole flap 14 and extend transversely to the longitudinal axis of the Shoe body 12. Selected ribs 62 of ribs 44 extend through the three connection points.
  • the sole flap lies against the bottom surface of the shoe body with the pretension of the tab. The pretension of the tab and the ribs extending in the transverse direction prevent the sole flap from inadvertently deflecting or pivoting out, while a rolling movement of the swimming shoe is not impeded due to the ribs extending in the transverse direction.
  • the outer portion 22 of the sole flap 14 also has two recesses 46 which are formed under the bridge 26 between the three ribs 62 which extend through the three connection points.
  • the shoe body 12 is formed symmetrically to a longitudinal central axis MA. In this way, it is possible to use an identical injection mold for a left and a right swimming shoe.
  • FIG 8 shows a perspective view of a swimming shoe 10 for the right foot according to a second embodiment.
  • the swimming shoe 10 consists mainly of two parts, namely the actual shoe body 12 and a sole flap 114 connected to it via a joint arrangement 18, which is described in more detail Figure 12 is shown separately.
  • the joint arrangement 18 has an elastic tab 120, via which the sole flap 114 is connected to the shoe body 12, the tab 120 elastically pressing the sole flap 114 with a prestress on a bottom surface 32 of the shoe body 12.
  • the flap 120 is again made integrally with the shoe body 12 using the injection molding process.
  • the shoe body 12 with the flap 120 is formed from a thermoplastic elastomer, preferably a thermoplastic elastomer based on urethane (TPU).
  • TPU thermoplastic elastomer based on urethane
  • the sole flap is designed as a plastic injection molded part.
  • the tab 120 in the form of a material flap has a uniform wall thickness and - depending on the material - a thickness d in the range from 3 mm to 5 mm.
  • Figure 9 shows a view of the swimming shoe 10 according to the second embodiment from below.
  • the sole flap 114 has an outer portion 122, to which the pivotable portion 130 of the tab 120 is fastened, and an inner portion 124, which rests against the bottom surface 32 of the shoe body 12 in the retired state. Sections 122 and 124 are separated from one another by pivot axis 116.
  • the sole flap 114 has two rows of elongated holes, each of which contains an inner elongated hole 50 and an outer elongated hole 52 in the direction transverse to the longitudinal direction of the shoe body. Furthermore, the pivotable section 130 of the tab 120 has two fastening tongues 142.
  • the fastening tongue 142 is braided into the elongated holes. More specifically, the fastening tongues 142 are each inserted into the corresponding inner elongated hole 50 from above and then inserted into the corresponding outer elongated hole 52 from below.
