Definitions

  • the invention relates to a binding for general cargo or load securing, in particular a one-way binding, consisting of a binding string or lashing strap and a tensioning device.
  • Wire bindings are used, for example, for bundling all types of piece goods into larger, compact storage and transport units, and for fixing and tying down loads on vehicles.
  • Wire bindings are known for this purpose, preferably made of stranded wire. This is looped around suitable fastening points and wrapped a few times around the main strand with the free end. The binding is tensioned by twisting the wires by means of a crossbar inserted through the strand and dividing it in the middle.
  • wire bindings also have a number of disadvantages. Due to its internal spring tension, wire is no longer easy to handle, especially over long lengths, and protruding wire ends can easily cause injuries. The small diameter of the wire strand leads to a strong local pressure load on the tied goods, under which the wire can cut into the goods and cause damage.
  • lashing straps which are preferably made of synthetic fibers, in particular polyester.
  • the wide contact surface between the lashing strap and the material to be tied prevents unwanted cutting.
  • the flexibility of the belt material enables the binding to be laid comfortably and safely, and the inherent elasticity of the plastic also absorbs mechanical peak loads due to elastic stretching.
  • a ratchet is usually used to fix such a lashing strap, through which one end of the lashing strap is pulled and then sewn to itself in the form of a loop.
  • the other end of the belt is tensioned by operating a lever on the ratchet.
  • This ratchet which is firmly attached to the lashing strap, is a comparatively expensive and complicated tool, the use of which only pays off if it is reused many times.
  • the webbing is always made up in fixed lengths, which considerably limits the flexibility in use for this type of binding.
  • the object of the invention is to provide a binding of the type mentioned, in which a lashing strap is fixed by a simple and cheap, easy-to-use tensioning device.
  • the tensioning device consists of two side plates which are arranged parallel and spaced apart from one another and one end of the lashing strap is guided over a winch which is recessed in two aligned recesses in the side plates of the tensioning device Guide openings are mounted and can be moved from a freewheel position into a latching position.
  • the lashing strap binding can also be used as a one-way binding without significant loss.
  • a commercially available webbing is used as the binding string.
  • the webbing can be supplied in rolls and cut to size on the spot.
  • the construction of the clamping device is very simple and enables inexpensive mass production. It can be designed in such a way that the lashing strap is held in a self-locking manner by friction and tension, without an adhesive or seam connection being necessary, and the tensioning device is actuated with a conventional tool that is separate from the tensioning device itself.
  • the basic components of the binding according to the invention are a lashing strap 1 and a tensioning device 2 for tensioning this lashing strap 1.
  • the tensioning device 2 consists of two side plates 3 arranged parallel and at a distance from one another and connected to one another, and a winch 5 mounted between these side plates 3 the lashing strap 1 is wound and tensioned by turning the winch 5.
  • two fastening webs 4, 4 ′ arranged next to one another are provided, which run between and transversely to the side plates 3 and connect them to one another.
  • the essential task of these fastening webs 4, 4 ' is to hold on to one end 6 of the lashing strap 1, this end 6 being held here in a self-locking manner by friction (FIG. 4).
  • the fastening webs 4, 4 ' preferably consist of a round material or they are rounded on the longitudinal sides facing away from one another in order to form a largely edgeless support surface for the lashing strap 1.
  • the other, to be tensioned end 7 of the lashing strap 1 is then placed around the material to be integrated, cut to a suitable length, inserted into a slot 11 in the winch 5, wound on the winch 5 and tensioned by rotating this winch 5.
  • a single fastening web (not shown) can also be provided.
  • one end of the lashing strap 1 is wrapped around the fastening web and sewn to itself in the form of a loop or placed as a double strand around the goods.
  • the side plates 3 of the tensioning device 2 are fastened (not shown) to one side of a platform, a pallet or the like on which the goods to be integrated are to be fixed.
  • one end of the lashing strap 1 is fixed on the other side of the platform or pallet or looped around a ring which is attached to the platform or pallet and fixed in a double strand around the goods.
  • An essential feature of the invention is the actual tensioning device formed by the winch 5.
  • This winch 5 extends between and across the side plates 3 and is mounted in opposite, aligned guide openings 10 which are recessed in the side plates 3.
  • the end of the winch 5 projects over the side plate 3 on at least one side in order to create an attack for a turning tool (not shown).
  • the winch 5 is locked against axial movement.
  • the part of the winch 5 lying between the side plates 3 is shaped as a coil former. This consists of a cylindrical middle part 9, which is provided with a slot 11 corresponding to the width of the lashing strap 1. This slot 11 is guided diametrically through the coil body of the winch 5 and meets its axis of rotation. The exciting end? the lashing strap 1 is pulled through the slot 11 and wound up by turning the winch 5, so that the lashing strap 1 is fixed by the static friction between several successive layers 12 of the belt material.
  • the winch 5 can be held by discs 13 with play on the side plates 3 of the tensioning device 2.
  • the diameter of the disks 13 is larger than the clear width of the guide openings 10.
  • These disks 13 can rest on the outer surfaces of the side plates 3 (FIG. 1). But they can also be arranged on the inside of the side plates 3 (not shown).
  • the winch 5 can also be held by other measures known to the person skilled in the art, for example by springs. When the winch 5 is held by springs, its locking position is secured and unintentional freewheeling position is prevented.
  • a shaft 14 is provided in the extension of the winch axis, which projects into the guide openings 10 and projects with at least one end 15 beyond one of the side plates 3.
  • the shaft 14 is provided with a locking toothing which interacts with the contour of the guide openings 10 for the rotation and locking of the winch 5.
  • the locking teeth preferably consist of a star, which is loosely mounted in the guide opening 10 such that it rotates from a freewheeling position (FIG. 2), in which the winch 5 rotates freely, into a locking position (FIGS. 3 and 4), in which the winch 5 is locked, can be moved and vice versa.
  • the guide openings 10 can be circular bores which are expanded to a catch 21 on part of their circumference.
  • the catch 21 lies on the entry side of the belt end 7 to be wound into the tensioning device 2, that is to say on the side facing away from the fastening webs 4.
  • the Starting from the circular circumferential section of the guide openings 10, catch 21 is more or less excluded from the side plates 3 as a step in the pulling direction of the belt end 7 to be tensioned.
  • a cut is made in the side plate 3 along a diameter of the circular bore in the desired step depth.
  • One edge 22 of the step therefore lies on the circular peripheral section, and the other edge 23 is offset outwards by the step height. This edge 23 is led back to the circular peripheral section with the formation of the detent 21 with an arc 24.
  • the circular bore can also be open at one point and form an insertion slot for the winch 5 (not shown).
  • the star 16 of the shaft 14 is adapted to this shape of the guide openings 10.
  • the outer circumference of the star 16 is designed as a toothed ring with at least two, preferably a plurality of teeth arranged at the same distance from one another.
  • the teeth 17, 18, 19, 20 are curved like sabers (FIG. 3) and the contact circle of the tooth tips is smaller in circumference than the circular bore of the guide openings 10.
  • the shaft 14 with the star 16 can therefore be lifted out of the catch 21 Turn the freewheel position (Fig. 2) with play in the circular hole.
  • the curvature of the teeth 17, 18, 19, 20 of the star 16 has approximately the same radius of curvature as the circular bore of the guide openings 10.
  • each tooth is drawn radially inwards starting from the tooth tip and jumps from its innermost point along a shaft diameter line outwards to the tip of the next tooth.
  • the jump height is slightly less than the step depth of the catch 21, so that the star 16 can mesh with one tooth 17 into the catch 21 (FIG. 3).
  • the shaft 14 is locked in this position against rotation against the direction of the arrow in FIG. 3.
  • the shaft 14 is lifted out of its locked position when it rotates in the direction of the arrow.
  • the outer edge of the next tooth 18 and in part also the tips of further teeth 19, 20 slide along the circular peripheral section of the guide openings 10.
  • the shaft 14 is moved more and more towards its freewheeling position (FIG. 2) within the circular bore of the guide openings 10 until the next tooth 18 reaches the catch 21 and engages therein.
  • the lashing strap 1 When the shaft 14 rotates, the lashing strap 1 is wound onto the winch 5 and thereby tensioned. The rotation of the shaft 14 and the associated deflection from the locking position takes place against the tensile stress of the wound lashing strap 1, which holds the shaft 14 in its locked position in the tensioned state.
  • the rotation of the shaft 14 is brought about with a suitable tool (not shown) which is separate from the clamping device 2 and which engages at one end or at both ends 15 of the shaft 14 which protrude beyond the side plate (s) 3.
  • Fig. 4 shows the insertion of the lashing strap 1 in the tensioning device 2.
  • the lashing strap is first placed with an end 6 in the form of a loop around a fastening web 4, pushed through the gap 8 between the fastening webs 4, 4 ', then around the second fastening web 4 'looped and finally pulled back out over the first fastening web 4 and thereby fixed.
  • the free end 7 of the lashing strap 1 is then placed around the material to be bundled (not shown), returned to the other side of the tensioning device 2, pulled through the slot 11 of the winch 5 and tensioned by turning the winch 5.
  • the clamping device 2 consists of metal or a solid plastic.
  • the binding according to the invention can be used both for bundling general cargo of all kinds into larger, compact storage and transport units and for fixing and tying down loads on vehicles.
  • bundling a simple, self-contained belt loop is placed around the material, one end of the belt being fixed to the fastening webs 4 and the other end of the belt being fixed to the winch 5 of the tensioning device 2.
  • the lashing strap 1 is usually stretched between two brackets.
  • two partial belts can each be looped around a holder and guided as a double strand to the tensioning device 2, where they are placed one above the other on the fastening webs 2 or wound on the winch.
  • the leadership in the double strand leads to a doubling of the binding capacity.
