Definitions

  • the invention relates to a belt for protecting people from falling, comprising a fitting part and at least a first and a second belt sub-element encompassing the body part, the fitting part comprising a body which is designed for connection to the first belt sub-element, with the second belt sub-element and with a flexible bridge.
  • the belts are used to protect climbers from falling.
  • the belts generally comprise several belt sub-elements that surround the body part, such as a hip belt, chest belt and/or leg loops.
  • the belt sub-elements are connected to one another using fittings and it is usually possible to attach further elements such as rope bridges to the fittings.
  • a fitting part is provided on the left and a fitting part on the right of the belt and the rope bridge is fastened between the fitting parts, depending on the design of the fitting part, using knots or loops at the ends of the rope bridge.
  • the rope bridge can therefore be used as an anchor point, e.g. hooked into a safety device, and the user can lean back securely.
  • Embodiments with shackles as fittings are known, with a webbing of the hip belt, a webbing of the leg loop and one end of the rope bridge being hung on a U-shaped body of the shackle during assembly.
  • the U-shaped body can be closed using a bolt so that the elements mentioned are fixed on the shackle.
  • the end of the rope bridge When assembled, the end of the rope bridge usually rests on the bolt.
  • the disadvantage of these embodiments is that all elements are released when the bolt is removed and that there are no dedicated strap openings and therefore all straps or the flexible bridge rub together.
  • the modularity of this embodiment particularly with regard to the interchangeability of the cable bridge, has always been viewed as a positive characteristic.
  • a fitting part that has an opening on one side.
  • a closing element can be inserted into the opening, which completes the shape of the fitting part and replaces a partition in the fitting part.
  • the closing element thus separates the bridge hole from an opening for an anchor point.
  • the webbing openings remain unchanged, as is the case with fittings with rigid bodies.
  • belts comprising fittings with bodies which are penetrated by two belt openings in the usual manner are difficult to manufacture or difficult to maintain.
  • the belt sub-elements must be provided with belt straps, with the ends of the belt straps being loose.
  • the webbings are then passed through the respective webbing openings of the fitting part and then sewn into a loop, with the fitting part being located in the loop.
  • the belt sub-elements can be permanently connected to the fitting part. Changing the fitting part and/or belt sub-elements for maintenance purposes is not possible.
  • a belt for protecting people from falling comprising a fitting part and at least a first and a second belt sub-element encompassing the body part, the fitting part comprising a body which is designed for connection to the first belt sub-element, with the second belt sub-element and with a flexible bridge, whereby the body is penetrated by a first webbing opening and by a bridge hole, the body of the fitting part comprising a first part and a second part, which can be brought into an assembled state and into a separated state, the first part and/or the second part at least one first external groove for the first belt sub-element, wherein in the assembled state of the two parts, the first groove is completed by the other part to the first belt opening passing through the body, in order to create a first belt therein to semi-permanently connect the first belt sub-element encompassing the body part to the fitting part.
  • the two-part fitting part of this belt enables the webbing opening separate from the bridge hole to be designed to be openable, which was previously not known from the prior art.
  • this makes it possible for the first time that the belt sub-elements can be completely manufactured before they are connected to the fitting part, i.e. the ends of the belt straps of the belt sub-elements can be sewn into loops in advance before they are connected to the fitting part.
  • connection is used herein synonymously with a “releasable” connection and is intended to emphasize that the two parts are usually not separated from each other in use, but can be separated before or after use, preferably by means of tools, for example by means of a screwdriver to loosen the screws described below.
  • the new fitting parts therefore create an opportunity to assemble or maintain the belt independently of the belt straps of the belt sub-elements.
  • the solution according to the invention is particularly advantageous when the end of the first webbing of the first belt sub-element, which is to be connected to the fitting part, is sewn into a loop.
  • both the first webbing of the first webbing sub-element and the second webbing of the second webbing sub-element would be received in the first webbing opening, which means that a second webbing opening can be omitted.
  • the straps touch each other, which can lead to wear and tear.
  • the first part and/or the second part preferably comprises at least one second external groove for the second belt sub-element, the second groove being in the assembled state of the two parts is completed by the other part to form a second webbing opening passing through the body, in order to connect a second webbing of the second belt sub-element encompassing the body part to the fitting part.
  • the body is penetrated by the first webbing opening (and possibly also by the second webbing opening) and by a bridge hole.
  • the first or second part is penetrated by the bridge hole, i.e. the bridge hole is not present as a groove on an outside of the part.
  • the flexible bridge can be anchored in the bridge hole using a knot.
  • the first part and/or the second part can comprise at least a third external groove for the flexible bridge, wherein in the assembled state of the two parts, the third groove is completed by the other part to form a bridge hole passing through the body in order to achieve this flexible bridge to connect to the fitting part. In this way, when assembling the fitting part, not only the straps of the belt sub-elements, but also the flexible bridge can be semi-permanently connected to the fitting part.
  • the body of the fitting part preferably has at least one transverse hole, which is arranged at a predetermined distance from a front and a back of the body, the transverse hole covering both the first part and the second Part penetrates, the fitting part further comprising a screw, the screw being able to be guided into the transverse hole and locked therein in order to connect the first part to the second part in the assembled state.
  • the transverse hole enters the body from a side surface and can thus run through both parts so that they can be connected by screws.
  • Screws with threads are particularly preferred because they can be easily loosened using a tool and at the same time offer a high level of protection against accidental loosening of the screw and subsequently the two parts.
  • the transverse hole can have an internal thread which, for example, is cut directly into the respective part.
  • the transverse hole could have an area with a larger diameter in which a screw nut is inserted which has the internal thread.
  • an adhesive could also be provided between the transverse hole and the screw, preferably between the thread of the screw and the internal thread of the transverse hole.
  • external connectors such as clamps could be used to semi-permanently connect the two parts together.
  • the fitting part also has a pulling direction, which is the direction in which the fitting part is mainly stressed when the belt is in use.
  • the fitting part is essentially symmetrical about the direction of pull, which also takes into account minor deviations from symmetry in order to adapt the fitting part to anatomical conditions. Since the greatest force acts on the screws in the pulling direction, it is preferred if the transverse hole is arranged at an angle to the pulling direction.
  • two transverse holes are used, each with a screw and the transverse holes are also symmetrical about the pulling direction, although this is not mandatory.
  • the two parts are also designed symmetrically about the pulling direction. In the simplest case, a simple definition of the pulling direction can be seen as a direction about which the body is mirror-symmetrical, whereby the webbing openings can deviate from the mirror-symmetry if necessary.
  • the screws or generally the connectors for the semi-permanent connection of the two parts are usually selected such that the fitting part can withstand a static force of at least 23 kN along the pulling direction.
  • the screws have a minimum diameter of 5 mm, for example. This is dimensioned for a case in which two screws are used, they are fully load-bearing in the tensile direction and the highest strength class is selected for the screws.
  • the body comprises a web that divides, i.e. passes through or bridges, the bridge hole.
  • This is particularly advantageous in combination with the third groove mentioned if the web is also open on one side when the two parts are separated.
  • an end of the flexible bridge that is preformed into a loop, in particular sewn, can be pushed onto the web.
  • this preformed loop of the flexible bridge can be securely anchored in the bridge hole.
  • the body of the fitting part as well as the parts are usually designed symmetrically about a pulling direction.
  • the web is preferably parallel to the pulling direction or axis of symmetry and particularly preferably the pulling direction or axis of symmetry runs through the web. This makes the bridge particularly easy to access, since the open end of the bridge is made accessible by separating the two parts.
  • the web is therefore preferably formed in one piece on the first part or on the second part and protrudes from the third groove.
  • the web could be formed as a separate element and, for example, be inserted as a pin between the first part and the second part.
  • the part opposite the web comprises a recess for receiving the web (in particular if the web has a diameter that is smaller than the thickness of the body) or for receiving an extension of the web in the assembled state of the parts , as this means that the bridge is supported on both sides and can therefore withstand greater loads.
  • a pin could be used which engages in a tubular web.
  • the aforementioned screw which connects the first part to the second part, can also perform a dual function and form the web when it passes through the bridge hole. This creates a particularly stable web that is more robust than a web that is formed in one piece on the second part.
  • the web in this embodiment will be located normal to the pulling direction, but an arrangement parallel to the pulling direction is also conceivable.
  • the first part and the second part preferably have interlocking guide surfaces at those points that touch each other in the assembled state of the two parts. These interlocking guide surfaces provide particular support for preventing the two parts from rotating relative to one another.
  • the body has a thickness, measured from the front to the back, of 6 mm to 14 mm, preferably 8 mm to 10 mm.
  • the transverse hole has a diameter of 5 mm to 10 mm, preferably 6 mm to 8 mm.
  • the harness described herein could be used for all possible purposes, its intended use as a climbing harness is particularly preferred.
  • the first belt sub-element is a hip belt and the second belt sub-element is a leg loop, with a webbing of the hip belt usually being located in the first webbing opening and a webbing of the leg loop being located in the second webbing opening.
  • this belt will have a further leg loop and a further fitting part, which can preferably be designed with two parts like the first-mentioned fitting part or in one piece according to the prior art.
  • a webbing of the hip belt is guided through a first webbing opening of the further fitting part and a webbing of the further leg loop is guided through a second webbing opening of the further fitting part.
  • This manufacturing process can also be used as part of a maintenance process in which one of the belt sub-elements or the fitting part is to be changed.
  • the two parts are first moved from the assembled state to the separated state and the loops are removed from the grooves and then the mentioned manufacturing process is carried out.
  • a screw is used as a web, it is first guided through a first section of the transverse hole and here preferably passes through both the first and that second part until the screw protrudes into the bridge hole. The screw is then passed through the loop of the flexible bridge located in the bridge hole. The screw is then further pushed through a second section of the transverse hole, which preferably passes through both the first and second parts. Finally, the screw is preferably screwed into the transverse hole or to a nut located outside the fitting part.

  • FIG. 1 shows a belt 1 for protecting people from falling, which in the embodiment shown is designed as a climbing belt, also referred to as a seat belt or holding belt.
  • This belt 1 includes a hip belt 2 and two leg loops 3, which are connected to the hip belt 2 via fittings 4.
  • the belt could, for example, also include further or other elements such as a chest strap, in which case the belt could be referred to as a safety harness.
  • the elements such as the hip belt 2, the leg loops 3 or a chest strap are referred to as belt sub-elements that surround the body part.
  • the strap sub-elements are usually designed as open straps, the ends of which are connected to a buckle 5 to form the strap into a loop that can be placed around a body part, as in Figure 1 is shown.
  • the belt sub-elements can be designed to be adjustable in size using a length adjustment device in the area of the buckle 5. Such embodiments can be provided for both the hip belt 2 and the leg loops 3.
  • the belt sub-elements are made of textile material and can, for example, be provided with a reinforcing leather part.
  • the fitting parts 4 are used as a connection point between the belt sub-elements.
  • the fitting parts 4 can thus simultaneously form a force transmission point between the body of the user of the belt 1 and an anchor point at which the user of the belt 1 is to be secured.
  • a fitting part 4 is usually provided on the left and a fitting part 4 on the right on the belt 1 and a flexible bridge 7 (such as one or more ropes or a webbing) is suspended between the fitting parts 4.
  • the bridge 7 can subsequently be attached to a stop point, which can be made easier if there is a ring 8 on the bridge between the fittings 4.
  • the bridge 7 is fixed in a bridge hole in the fitting part 4 by knotting the bridge at the ends, see knots 9 in Figure 1 . The length can be adjusted by positioning the knot.
  • the lower belt elements In order to connect the lower belt elements to one another or to the fitting parts 4 and thereby enable good force transmission, the lower belt elements usually have belt straps 6 which, for example, run through the entire lower belt element. This achieves, in particular, good force transmission between the belt straps 6 of a belt sub-element and the body of a user.
  • the hip belt 2 ie the first belt sub-element
  • the leg loops 3 ie the second belt sub-elements
  • the first webbing and the second webbing connect the hip belt 2, ie the first belt sub-element, and the leg loops 2, ie the second belt sub-elements with the fitting part 4.
  • the first webbing and the second webbing could also be made of different materials.
  • FIGs 2a and 2b show how the straps 6 are connected to the fitting parts 4 if, as is usual in the prior art, these are non-openable elements are carried out.
  • Figure 2a shows that the webbing 6 must first be guided through webbing openings in the fitting parts 4. Only then can the ends of the straps 6 be sewn into a loop, as in Figure 2b is shown in order to establish a secure connection between the belt sub-elements and the fitting part 4.
  • the mutual connection of the belt sub-elements via the fitting parts 4 is therefore designed to be inseparable, which means that one of the elements cannot be changed subsequently.
  • this manufacturing process has the disadvantage that the loops on the webbing 6 cannot be produced in advance, which would be advantageous in terms of process technology.
  • a fitting part 10 which comprises a body 11 which has a first part 12 and a second part 13.
  • the body 11 and subsequently also the parts 12, 13 are preferably made of metal and are further preferably designed as flat parts.
  • Such a flat body 11 usually has a thickness, measured from a front side V to a back side R, of 6 mm to 14 mm, preferably of 8 mm to 10 mm. Since it is a flat body, the thickness is usually the smallest distance from external surfaces.
  • the parts 12, 13 also have this thickness, so that this is also preferably the smallest distance from outer surfaces for the parts 12, 13.

  • the bridge hole B, 20 can be divided by a web 25, that is, it can be penetrated by a web 25 or it can be bridged by a web.
  • a detachable bridge can be used to bridge the bridge hole B, 20, as in the EP 3 332 840 A is shown. Novel other embodiments for the web are described below.
  • a web 25 is by no means necessary, as in the case for example Figures 3a, 3b , 11a, 11b is shown.
  • a stopper knot is usually provided at one end of the flexible bridge 7, which prevents the flexible bridge 7 from being pulled through the bridge hole 20.
  • a web 25 can also be provided when using a bridge 7 with a stopper knot in order to make the bridge hole 20 smaller and prevent the stopper knot from slipping through.
  • the Figures 9a, 9b , 12a, 12b show embodiments in which the bridge hole 20 is penetrated by a web 25.
  • the bridge hole 20 is designed to be openable, ie the first and/or the second part 12, 13 have the third groove 21 mentioned, so that the bridge hole 20 passes through the body 11 in the assembled state.
  • the web 25 is designed in such a way that it is open on one side of the third groove 21 when the two parts 12, 13 are separated.
  • the web 25 is preferably parallel to the mentioned pulling direction Z1 or axis of symmetry. In these cases, a loop formed at the end of the flexible bridge 7 can be hung on the web 25 when the two parts 12, 13 are separated.
  • the loop of the flexible bridge 7 is enclosed between the two parts 12, 13 in the body 11.
  • the flexible bridge 7 cannot therefore be removed from the fitting part 10 when the two parts 12, 13 are in the assembled state.
  • the two parts 12, 13 are brought into the separated state, which can take place, for example, by opening the screws 22 mentioned.
  • a web 25 can also be used, for example, in the embodiments of Figures 3a, 3b are used.
  • the web 25 can also have an extension 26, which can engage in a recess 27 of the other part 12, 13 in order to increase the stability of the body 11 in the assembled state of the two parts 12, 13.
  • the web 25 could also have a smaller diameter than the thickness of the body 11 and thus be inserted into the recess 27 - assuming the stability of the resulting fitting part required by the use in personal fall protection.
  • the web 25 could, for example, be tubular and instead of a recess 27, the other part 12, 13 has a pin that fits into the tubular web 25. The pin can then be pushed into the tube when the two parts 12, 13 are joined together.
  • the web 25 can also be formed by the aforementioned screw 22, which connects the two parts 12, 13 to one another.
  • the transverse hole 23 passes through both parts 12, 13 on both sides of the bridge hole 21, so that a single screw 22 connects the parts 12, 13 to one another at two different points.
  • the screw 22 can therefore pass through the bridge hole 20.
  • This variant, in which the screw 22 passes through the bridge hole can be used as in the Figures 10a, 10b shown can be used with an openable bridge hole 20 or as in the Figures 13a, 13b shown at a static bridge hole B.
  • the Figures 1 la-13b show three variants for producing the belt 1 with three different fitting parts 10. All three variants have in common that initially at least two belt sub-elements are provided with belt straps 6, the ends of the belt straps 6 preferably being preformed into loops. Furthermore, the fitting part 10 is provided, with the parts 12, 13 being in a separate state.
  • a fitting part 10 is provided, in which the first webbing opening 15 and the second webbing opening 18 are designed to be openable.
  • the bridge hole B is provided as an opening which permanently penetrates the second part 13 and cannot be opened by separating the parts 12, 13.
  • the loop 14 of a webbing 6 is inserted into the first groove 16, which will later form the first webbing opening 15.
  • the loop 14 of the other webbing 6 is inserted into the second groove 16, which will later form the second webbing opening 18.
  • the two parts 12, 13 are then brought into the assembled state and, if necessary, connected using the screws 22.
  • the flexible bridge 7 can be guided through the bridge hole 20 and knotted or provided with a prefabricated knot and guided through the bridge hole 20 with the untied end. It goes without saying that this embodiment could also be implemented with an openable bridge hole 20.
  • the fitting part 10 could then be as in the Figures 3a, 3b be carried out, whereby a web 25 could optionally run through the bridge hole 20, which in this case would serve to make the bridge hole 20 smaller so that the stopper knot is better secured.
  • a fitting part 10 is provided, in which the first webbing opening 15, the second webbing opening 18 and the bridge hole 20 are designed to be openable.
  • a permanent web 25 is formed on the third groove 21, which is designed to be open on one side.
  • the loop 14 of a webbing 6 is inserted into the first groove 16, which will later form the first webbing opening 15.
  • the loop 14 of the other webbing 6 is inserted into the second groove 16, which will later form the second webbing opening 18.
  • a flexible bridge 7 is provided, one end of which is preformed into a loop. The loop of the flexible bridge 7 is pushed onto the web 25.
  • the two parts 12, 13 are then brought into the assembled state and, if necessary, connected by means of the screws 22.
  • a fitting part 10 is provided, in which the first webbing opening 15 and the second webbing opening 18 are designed to be openable.
  • the bridge hole B is static, but could also be opened as in the Figures 10a, 10b be trained. No permanent web is formed in the bridge hole B, but rather this is formed by a screw 22 which can be inserted into the body 11.
  • the loop 14 of a webbing 6 is inserted into the first groove 16, which will later form the first webbing opening 15.
  • the loop 14 of the other webbing 6 is inserted into the second groove 16, which will later form the second webbing opening 18.
  • the two parts 12, 13 are then brought into the assembled state.
  • the screw 22 is then guided through a first section of the transverse hole 23 until it protrudes into the bridge hole B. Thereafter, a flexible bridge 7 is provided, one end of which is preformed into a loop, and the loop is inserted into the bridge hole B. The screw 22 is then further pushed through the loop and the second section of the transverse hole 23 and screwed into an internal thread in this second section or with a nut located outside the fitting part.
  • the flexible bridge 7 is shown as a rope bridge. This is preferred for making a knot 9.
  • the flexible bridge 7 is shown as a webbing, the end of which is sewn into a loop.
  • this could be implemented in the same way if the flexible bridge 7 is formed by one or more cables, which usually corresponds to the preferred embodiment.
  • the ends of the webbing 6 are (pre-)sewn into loops.
  • buckles or the like could also be used to form the ends of the webbing 6 into loops.
  • the fitting parts 10 according to the invention further enable an advantageous assembly or an advantageous maintenance of the belt 1.
