Definitions

  • the present invention relates to a trapezoidal belt with a shell-shaped back part, which is mirror-symmetrical to an axis parallel to the body longitudinal axis of the user, preferably with abdominal belt parts arranged on both sides transversely to the axis of symmetry.
  • trapezoidal belts have long been known in practice. They are generally used by water sports enthusiasts on sailboats or surfboards to place them around the hull of the water sports enthusiast and connect it to a part of the watercraft. Such a trapezoidal arrangement makes it possible for the water sports enthusiast to ride far beyond the side wall or the surfboard when he is sailing hard on the wind with his watercraft, in order to achieve a favorable center of gravity. The use of a trapeze means a lot of relief for the arms.
  • Known trapezoidal belts are made of a foamed plastic, which is surrounded by a tear-resistant shell that serves as surface protection.
  • a disadvantage of such trapezoidal belts is that they adapt poorly to the shape of the body and thus tend to slide up on the body of the water sports enthusiast, which occurs in particular when there is little wind and strong uphills, since the tractive force acting on the trapezoidal hook is then directed particularly steeply upwards. There is also a risk of slipping up when starting water with a surfboard. The buoyancy of the water pushes the trapezoidal belt up where it gets stuck when the surfer is standing on the board. The trapezoidal belt must then be pulled down actively by hand, which in particular in strong winds, the surfer loses control of the board. In the case of poorly fitting trapezoidal belts, there is also the disadvantage that the wind blows between the body and the back part, which exposes the surfer's kidneys to the risk of preservation.
  • the back part is provided with an inwardly curved lumbar support part extending along the axis of symmetry.
  • the trapezoidal belt adapts to the course of the spine and uses the inward curvature of the spinal column in the lumbar region to create a positive connection with the human body with regard to the displacement of the trapezoidal belt upwards or downwards. Due to the deep arrangement of the curvature in the Back part of the trapezoidal belt is simultaneously ensured that the area of the kidneys of the human body is covered by the trapezoidal belt without a gap, so that coldness of the kidneys is prevented by this arrangement of the curvature.
  • the back part is formed from two flexible plates arranged symmetrically to the axis, the mutually facing longitudinal sides of which, along the axis of symmetry, each have a recess extending downwards from the top edge of the back part, opening towards the top edge, and a downward opening thereon have a subsequent recess opening towards the lower edge of the back part, the long sides of the respective plates being connected to one another to form the lumbar support part.
  • This embodiment practically represents the basic shape of the trapezoidal belt according to the invention. With this configuration, the trapezoidal belt can have the outer contours of a kidney belt known from motorcycling. In this simple embodiment, the plates can have an identical cut. The recesses up and down in the back are then the same size.
  • This type of design of the trapezoidal belt according to the invention is also particularly suitable for smaller series, although it would also be conceivable, particularly for the large-scale production of such trapezoidal belts, to produce them by foaming in a mold or, in the manner of producing an integral foam part, by injection molding into a mold.
  • the two flexible plates always have the same cutting pattern and can therefore be punched out with a tool.
  • the connection of the long sides of the two flexible plates inevitably forms the ge arched lumbar support part.
  • the inward arched lumbar support part is under a certain tension due to the connection of the mutually facing longitudinal sides, which effectively prevents the inward arched lumbar support part from bulging outwards.
  • the back part is formed from two flexible plates arranged symmetrically to the axis, the mutually facing longitudinal sides of which are longitudinal the axis of symmetry each have a long, narrow, semi-oval recess extending downward from the upper edge of the back part and a short, adjoining triangular recess extending to the lower edge of the back part, the long sides for forming the lumbar vertebral support part with each other are connected.
  • the interaction of the lower, short, triangular recess with the upper, long, semi-oval recess causes the trapezoidal belt to adapt not only to the lumbar region, but to the entire human back.
  • the length of the long, narrow recess is preferably chosen to be five times as long as the length of the short triangular recess.
  • Another embodiment of the invention is particularly suitable for trapezoidal belts, which are designed as seat trapezium, with a seat part extending downwards from the back part, according to which the back part is formed from two flexible plates arranged symmetrically to the axis, the longitudinal sides of which face each other along the axis of symmetry one from the top of the back have partly downwardly extending short triangular recess and an adjoining downward, reaching into the seat part, long, narrow, semi-oval recess, the long sides for forming the inwardly curved lumbar support part are connected to each other. It is thus achieved in a simple manner for trapeze harnesses that they fit snugly to the body and do not tend to slide down when no tractive force acts on the trapezoidal hook.
  • At least one second band likewise connecting the abdominal belt parts.
  • This has the advantage that the trapezoidal belt fits snugly against the body of the water sportsman even when no tension has yet been applied via the band provided with the fastening hook and connected to the watercraft.
  • This hooked band generally connects the two parts of the abdominal belt only very loosely, in order to avoid constricting the waist of the water sports enthusiast when a great pulling force acts on the trapezoidal belt.
  • the second band since it is only intended to hold the two abdominal belt parts together, can be made smaller than the first band and therefore also be arranged under this.
  • the advantage of the second volume is particularly noticeable when the surfer swims in the water when the water starts and the trapeze belt tends to slide upwards due to the buoyancy. This is counteracted by the second belt and is achieved in that the harness belt fits perfectly during the start and does not have to be adjusted after the start.
  • Both the second band connecting the abdominal belt parts and the band of the back part can each be provided with a Velcro fastener.
  • FIG. 1 shows a trapezoidal belt 1 according to the invention according to a first embodiment with two wing-shaped abdominal belt parts 2 and 3, which extend transversely to a back part 4 and, in the tightened state, surround the user's hip area up to the abdomen. Above the back part extend two upwardly U-shaped shoulder parts 5 and 6, which in the tightened state extend from the back part 4 over the shoulders of the user to the chest side.
  • a wide webbing 7 is fastened to each of the abdominal belt parts 2 and 3, of which one 6 has a hook 8 which is intended for hanging in a rope or the like on the watercraft.
  • the straps 7 can be connected to one another via a closure.
  • a further band 9 or 10 which is covered by the belt straps 7 when the trapezoidal belt 1 is tightened.
  • the tapes 9 and 10 can be connected to a Velcro fastener 11 in the embodiment shown here.
  • the back part 4 is provided with an inward curvature, the lumbar support part 12, which is particularly strongly formed below the belt straps 7 (cf. FIG. 4).
  • a strap 13 spanning the lumbar support part 12 is fastened to the back part 4 and is also adjustable in length with a Velcro fastener 14.
  • the exemplary embodiment of the trapezoidal belt 1 according to the invention shown here consists, among other things, of two flexible plates 16 and 17 which are mirror-symmetrical to an axis 15 parallel to the body axis of the user and which each consist of layers of foam bonded in layers.
  • the cutting pattern 18 of the two flexible plates 16 and 17 can be seen from FIG.
  • the cutting pattern 18 shows in its upper region half of the upwardly U-shaped shoulder parts 5 and 6 and further below one of the wing-shaped abdominal belt parts 2 and 3 oriented transversely to the axis of symmetry 15, also shown.
  • a long, narrow, semi-oval recess 19 which extends from the upper edge 21 of the back part 4 to approximately 5/6 of the total length of the back part, is arranged in the cutting pattern 18 in the longitudinal side 23 facing the axis of symmetry.
  • a triangular, short recess 20 is arranged below the recess 19, the length of which corresponds to approximately 1/6 of the total length of the back part 4 and thus extends to the lower edge 22 of the back part 4.
  • the depth of the long, semi-oval recess 19 is only a few millimeters, approximately 1/50 to 1/100 of the total length of the back part 4.
  • the depth of the triangular recess 20 on the lower edge of the back part 4 is approximately 1/20 to 1/40 the total length of the back part 4.
  • the depth of the recesses varies with the size of the harness belt. With large trapezoid belts, the depth of the recesses increases, with small ones.
  • FIG. 6 shows the pattern 24 of a second embodiment, which is intended for those trapezoidal belts that have no shoulder parts.
  • the shape of these trapezoidal belts rather corresponds to the kidney belts known from motorcycling.
  • the back part 4 is followed by an abdominal belt part 2 transversely to the axis of symmetry 15.
  • the blank 24 is also symmetrical about an axis 25 oriented perpendicular to the axis of symmetry 15.
  • an upwardly opening approximately triangular recess 19 is formed on the long side 23 of the back part 4.
  • the back part 4 has on its longitudinal side 23 a downwardly opening, also triangular recess 20.
  • the recesses 19 and 20 are each designed to be open toward the upper edge 21 and the lower edge 22 of the back part 4.
  • FIG. 7 shows a top view of a blank 26 for a third embodiment of the trapezoidal belt according to the invention.
  • the cut 26, which, like the cuts 18 and 24, shows only half of a trapezoidal belt, is intended for so-called trapezoids.
  • the blank 26 has a seat part 27 which extends downwards.
  • This recess 19 essentially corresponds to the recess 19 in the blank 24 shown in FIG. 6.
  • the recess 19 is followed by a semi-oval, long, narrow recess 20 which extends into the seat part 27.
  • the blanks 18, 24 and 26 are basically constructed in the same way. Therefore, identical reference numerals are used for the same or similar parts.
  • FIG. 3 now shows a rear view of the trapezoidal belt 1 glued together from the two flexible plates 16 and 17 according to the first embodiment.
  • the trapeze belt of the The second and third embodiment look the same, with the exception of the special features just described.
  • FIGS. 4 and 5 Due to the recesses 19 and 20 described above, after the two flexible plates 16 and 17 have been glued together along their long sides 23, the formation of the lumbar vertebral support part can be clearly seen in FIGS. 4 and 5.
  • a human spine is also shown in FIG. 4.
  • the design of the lumbar support part 12 according to the first embodiment shown in FIGS. 4 and 5 corresponds to the design of the lumbar support part of the second and third embodiment with the exception of the special features described above.
  • the mode of operation of the invention is described below with reference to the first exemplary embodiment.
  • the lumbar support part 12 adapts to the human body in the region of the lumbar vertebrae.
  • a variation in the strength of the curvature can be achieved in that the band 13 attached to the outside of the back part 4 is shortened or lengthened.
  • a stiffening of the lumbar support part 12 is achieved at the same time.
  • the trapezoidal belt 1 also fits properly when the belt straps 7 and their seams are stretched by large tensile forces acting on the hook 8, so that the belt straps 7 only loosely support the two belly connect belt parts 2 and 3.
  • the foamed flexible plates 16 and 17 it is possible for the foamed flexible plates 16 and 17 to be surrounded with a tear-resistant covering material before they are provided with the straps and straps.
