Definitions

the present invention relates to a climbing element with at least one through-opening running from a visible side to a rear side of the climbing element, with a reinforcing element being arranged on or in the through-opening, which has a through-opening arranged concentrically to the through-opening and with one end of the reinforcing element forming a screw head counterhold.
the invention also relates to a climbing system with at least one climbing element mounted on a climbing wall.
Artificial climbing systems for climbing and bouldering have climbing walls to which different climbing elements, such as handles and volume bodies, are attached.
the respective climbing wall usually consists of individual multiplex panels that are mounted on a stable framework.
the climbing elements are usually attached to the climbing wall by means of a screw connection that can be released again.
the climbing elements can be easily exchanged and/or rearranged on the climbing wall at any time. This means that different climbing routes can be displayed on the basis of an unchanged climbing wall.
the climbing element is either screwed into a nut worked into the multiplex panel of the climbing wall with a machine screw or fastened with a wood screw, which is screwed directly into the wood of the multiplex panel.
the operator of a climbing wall typically changes the climbing routes every two to four weeks. With a regular service life of a climbing wall of 10 years, a single climbing element can be screwed to and removed from the climbing wall hundreds of times.
Smaller climbing elements are mainly manufactured using the casting process using thermosetting plastics such as polyurethane or synthetic resin.
the production of smaller climbing elements in the casting process can thus still be managed with a reasonable amount of effort, even in large quantities.
the climbing elements which are cast with duroplastic plastic, have through-holes through which a wood or machine screw can be inserted in order to screw the climbing element to a climbing wall.
a reinforcement element which is arranged in or on the passage opening.
Reinforcement elements used for this purpose have a feed-through opening which is arranged concentrically with the through-opening running from the visible side to the back of the climbing element.
a screw for fastening the climbing element to a climbing wall can be passed through this feed-through opening.
One end of the reinforcement element forms a screw head counterhold, which is pressed by the screw head of the fastening screw when the climbing element is fastened to a climbing wall.
a climbing grip which has a grip body with an opening into which a clamping body is introduced.
the force exerted by a fastening means acts on the clamping body, as a result of which the grip body can be fitted without tension.
a break-resistant climbing hold based on elastomers is known from the publication DE 10 2011 008 098 A1 known.
a large number of wires are embedded in the material of the handle body.
the wires serve to reinforce the climbing hold and prevent parts of the climbing hold from falling down in the event of a break.
Metal inserts are often used to reinforce fastening openings in fiber composites. From the pamphlet DE 24 33 084 B2 a metal insert with a cylindrical shaft and a circular disk attached thereto is known. This insert is glued into the opening to be reinforced, with the circular disc being flush with the surface of the component.
the pamphlet U.S. 6,074,327 describes a climbing hold in which a reinforcement sleeve is passed through the through-opening. Such a reinforcement sleeve can easily be integrated in the through opening of a climbing hold when producing a climbing hold using the casting process.
macros are mainly made of (glass) fiber reinforced Plastic laminate made. Manually producing a single macro, layer by layer, can take several hours. Suitable reinforcement elements are laminated in during the manufacturing process to reinforce the through-openings. However, the laminated reinforcement elements can burst out of the brittle plastic laminate if the fastening screws are tightened and loosened suddenly with a cordless screwdriver. The fulfillment of the safety requirements by the relevant climbing element is then no longer guaranteed, as a result of which it must be withdrawn from circulation.
a climbing element with at least one through-opening running from a visible side to a rear side of the climbing element, on or in which a reinforcing element is arranged, which has a through-opening arranged concentrically to the through-opening, one end of the reinforcing element forming a screw head counterhold, wherein the climbing element is predominantly made of thermoplastic material, with either the reinforcing element being composed of a counter-retaining element having the screw head and a tubular rivet protruding from the rear into the through-opening, with a collar of the tubular rivet resting on the rear of the climbing element and one opposite the collar of the tubular rivet located free end portion of the tubular rivet is passed through the counter-retaining element and beaded, or the reinforcing element is a single element that is on the visible side of the climber ementes is pressed with its underside into the plastic of the climbing element, with an upper side of the reinforcing element being at least partially covered by the plastic.
the climbing element according to the invention is predominantly made of thermoplastic material, it can be produced inexpensively in an injection molding or in a deep-drawing process manufacture.
the production of large climbing elements, such as macros, benefits in particular from this, as this replaces tedious manual production.
the present invention also provides a particularly safe and durable climbing element, since the through-opening running from the visible side to the back of the climbing element is reliably provided with the reinforcement element, so that the climbing element permanently withstands the recurring, heavy stresses of loosening and fastening on a climbing wall.
the reinforcing element is composed either of a counter-retaining element having a screw head counter-retention and a tubular rivet, or it consists of a single element which is pressed into the thermoplastic material. In both cases, the reinforcement element can be easily and yet reliably integrated into the climbing element.
a free end of the tubular rivet is guided from the back through the through-hole of the climbing element and through the counter-retaining element forming the screw head counter-retention and beaded on the visible side of the climbing element, whereby the counter-retaining element is fixed to the through-opening of the climbing element.
the collar of the tubular rivet lying opposite the free end of the tubular rivet lies flat on the back of the climbing element, so that the reinforcement element is fixed on both sides at the ends of the through-opening.
the through-openings in the climbing element can either be drilled into the climbing element after it has been shaped by injection molding or deep-drawing, or they can be produced in the shaping process itself. For example, the through openings can be left out during injection molding.
Washers, rosettes, spring washers or nuts are particularly suitable as counter-holding elements.
numerous other objects that have a lead-through opening and a screw head counter-hold also come into consideration.
hollow-cylindrical objects such as insert sleeves that are inserted into the through-opening from the visible side are also suitable and which have a collar that lies flat on the visible side of the climbing element and represents a suitable counterhold for the screw head.
the screw head counterhold offers a bearing surface for a screw head of a screw with which the climbing element is fastened to a climbing wall. If the screw is tightened when attaching the climbing element to a climbing wall, the underside of the screw head presses against the screw head counterhold of the counter-retaining element. There is therefore no direct stress on the passage opening of the climbing element from the screw head.
the lead-through opening of the counter-holding element is arranged concentrically to the through-opening of the climbing element.
the diameter of the lead-through opening preferably corresponds to the diameter of the through-opening of the climbing element minus the wall thickness of the tubular rivet used for attachment.
the reinforcement element In the case of the climbing element according to the invention, a fastening of the reinforcement element is also provided in which no tubular rivet is used.
the reinforcement element consists of only one element, namely the counter-holding element itself.
the reinforcement element which consists of only a single element, is pressed with its underside on the visible side of the climbing element into the still deformable thermoplastic material until the thermoplastic material overflows onto the upper side of the reinforcement element as a result of displacement from the edge of the reinforcement element. After cooling down, the partially sunk reinforcement element sits firmly in the plastic and is thus reliably secured against falling off or slipping.
Both variants of attachment guarantee a durable arrangement of the reinforcement element on the passage opening of the climbing element, which also permanently withstands frequent, jerky shearing when attaching and detaching the climbing element on a climbing wall with a cordless screwdriver.
the climbing element according to the invention is also significantly more environmentally friendly than currently customary climbing elements.
the climbing element according to the invention can preferably be produced from acrylonitrile butadiene styrene plastic (ABS) and/or polycarbonate (PC) from recycling material.
ABS acrylonitrile butadiene styrene plastic
PC polycarbonate
the invention represents a climbing element that is significantly more cost-effective, safer and at the same time more environmentally friendly than the prior art.
the counter-retaining element has a screw head receptacle in the shape of a truncated cone.
the truncated cone-shaped screw head mount forms a precisely fitting screw head counterhold.
the countersunk head lowers into the truncated cone-shaped screw head socket. This can prevent a sharp edge of the screw head protruding over the lead-through opening after tightening, on which a climber could injure himself.
a rosette can preferably be used as a suitable counter-holding element with a screw head receptacle in the shape of a truncated cone.
the counter-holding element is located in a depression. This ensures that the counter-holding element protrudes less high on the visible side of the climbing element. On the one hand, this reduces snagging and thus the risk of injury for a climber, and on the other hand, visual perception is improved because the counter-support element is less clearly perceptible.
the counter-retaining element is fastened in the depression with adhesive. If the counter-holding element is fastened to the through-opening of the climbing element with a tubular rivet, the counter-holding element is reliably secured against falling off, but under certain circumstances it could still be twisted within the depression around the through-opening. This twisting in the depression can be prevented if the counter-retaining element is additionally fastened in the depression with adhesive.
an impact-resistant adhesive is used that can withstand jerky shearing that can result from using a cordless screwdriver.
the climbing element is deep-drawn.
the advantage here lies in a particularly favorable production of the climbing element according to the invention in the deep-drawing process.
This particularly benefits the production of large climbing elements, such as so-called “macros” or "volumes", since this replaces the time-consuming, manual production of individual pieces.
the deep-drawing is preferably carried out from thermoplastic sheets, such as ABS sheets with a thickness between 3 and 10 mm.
the fact that the climbing elements are always manufactured in the same way using the deep-drawing process also guarantees a consistently high product quality that is free of the individual fluctuations that are inherent in manual single-piece production.
the climbing element has a hollow handle body around which a flange is formed, through which the at least one through-opening is passed.
This embodiment can be produced particularly favorably both in a deep-drawing process and in an injection molding process.
This embodiment of the invention provides a particularly light climbing element which can be manufactured using little material.
the flange formed around the hollow handle body offers a planar and flat bearing surface for the climbing element on a climbing wall. Several through-openings can easily be made through the flange, as a result of which the climbing element can be securely fastened to a climbing wall.
the counter-holding element is made of metal or ceramic.
This climbing element according to the invention with a equipped with a particularly hard-wearing reinforcement element.
suitable counter-holding elements made of metal or ceramics such as solid metal rosettes or washers made of stainless steel or ceramics, are commercially available in a wide variety of designs. This enables the climbing element according to the invention to be produced inexpensively.
a particularly preferred embodiment of the invention provides that a coating of an epoxy resin primer layer and a quartz sand epoxy resin top layer is formed on the visible side of the climbing element.
the epoxy resin primer layer serves as a primer, on which the actual top layer is applied.
the top layer consists of a mixture of quartz sand and epoxy resin, which creates a rough surface texture. Since quartz sand is added to the top layer, it could easily flake off if applied directly to the plastic. However, this is reliably prevented by first applying an epoxy resin primer layer to the plastic, to which the quartz sand epoxy resin layer is then applied.
the object is also achieved by a climbing system with at least one embodiment of the climbing element according to the invention mounted on a climbing wall, wherein the climbing element is fastened to the climbing wall by a screw guided through the at least one through-opening.
the Figures 1 and 2 schematically show a possible embodiment of the climbing element 1 according to the invention in a side view ( figure 1 ) and a plan view ( figure 2 ).
the climbing element 1 shown is a macro which was drawn from a 5 mm thick ABS plate by vacuum forming.
the climbing element 1 has a hollow handle body 10 around which a flange 13 is formed.
the handle body 10 bulges out from the flange 13 .
the flange 13 is flat.
plates made of other thermoplastics can be used to manufacture the climbing element 1 using a deep-drawing process.
the thickness of the plate used depends on the size of the climbing element 1 and also depends on how far the wall thickness of the resulting handle body 10 is reduced during deep-drawing compared to the original thickness of the plate.
the climbing element 1 is also particularly suitable to manufacture the climbing element 1 using an injection molding process.
the flange 13 forms in the Figures 1 and 2 shown embodiment a wide, flat strip through which several through-openings 2 are passed.
the flange 13 is 2 cm wide, but it can also have a different width, for example in a range from 1 cm to 5 cm.
the width of the flange 13 can vary over its course. The sizing and the exact shape of the flange 13 depends primarily on the size and shape of the handle body 10.
the flange 13 is provided with a plurality of through holes 2 distributed around the handle body 10 .
the through-openings 2 serve as attachment points for the climbing element 1.
the through-openings 2 can be arranged equidistantly around the handle body 10 and/or depending on the expected application of force, so that there are more attachment points where there is higher stress than in areas with less stress are formed, or where no or only low forces occur, no attachment points are formed.
the through-openings 2 can be drilled or punched into the flange 13 after the deep-drawing. In the case of production using an injection molding process, the through openings 2 can already be given to the climbing element 1 during the injection molding process by means of a corresponding design of the mold.
the climbing element 1 On the visible side 11 of the climbing element 1 there is a coating of an epoxy resin primer layer 14 and a quartz sand epoxy resin top layer 15 . This gives the surface of the climbing element 1 a rough and non-slip surface texture, which offers a climber a non-slip stand on or a non-slip grip on the climbing element 1 according to the invention.
the climbing element 1 is in the in the figure 1 shown embodiment screwed directly to the wooden panels of a climbing wall 20 with screws 16. No nuts are therefore required on the climbing wall side for fastening the climbing element 1 to the climbing wall 20 and the climbing element 1 can be positioned anywhere on the climbing wall 20 .
the climbing element 1 is screwed to drive-in nuts with machine screws, which are driven in distributed over the climbing wall 20 .
figure 3 shows the area of a through opening 2 of an embodiment of the climbing element 1 according to the invention.
the through hole 2 is located in the flange 13 formed around the hollow handle body 10 .
the through-opening 2 runs from a visible side 11 of the climbing element to a rear side 12 of the climbing element through the thermoplastic material 4 of the climbing element 1.
a depression 9 is formed around the passage opening 2 on the visible side 11 of the climbing element 1 .
the depression 9 can either be milled into the flange 13 following the shaping of the climbing element or can already be formed during the shaping using the injection molding or deep-drawing process.
a counter-retaining element 5, which is fixed to the through-opening 2 with a tubular rivet 6, serves as the reinforcing element 3.
the tubular rivet 6 is inserted into the through opening 2 from the back 12 of the climbing element 1 .
the collar 61 of the tubular rivet 6 lies flat on the back 12 of the climbing element 1 .
the free end 62 of the tubular rivet 6 is passed through the counter-holding element 5 and then crimped.
the counter-holding element 3 is held securely at the through-opening 2 by the tubular rivet 6 .
the reinforcement element 3 formed from the tubular rivet 6 and the counter-retaining element 5 has a passage opening 31 for the passage of a screw 16 .
a solid metal rosette with a truncated cone-shaped screw head receptacle 7 serves as a counter-holding element 5, which offers a countersunk screw with a precisely fitting screw head counter-stop 32.
a flat washer serves as a counter-support element 5.
a large number of alternative counter-holding elements 5, such as nuts, insert sleeves or spring washers, can be used in the specific embodiment of the invention. In this way, precisely fitting counter-holding elements 5 can be selected for different fastening means.
the counter-holding elements 5 are preferably made of metal or ceramics, but other sufficiently hard and durable materials can also be used for their construction.
the full metal rosette is in the in figure 3 shown embodiment additionally secured with adhesive 8 in the depression 9. This can prevent the all-metal rosette, or any other counter-holding element 5, from twisting when fastening and detaching the climbing element 1 according to the invention on a climbing wall 20 in the depression 9.
an impact-resistant adhesive is particularly advantageous.
FIG 4 the region of the through-opening 2 provided with a reinforcement element 3 of a further embodiment of the climbing element 1 according to the invention is shown schematically.
the counter-holding element 5 is fastened without an additional tubular rivet 6 .
the reinforcement element 3 is identical to the counter-retaining element 5 in this embodiment.
the counter-holding element 5 is pressed with its underside into the thermoplastic material 4, which has been heated to deformability, until this swells over the edge of the counter-holding element 5 as a result of displacement and runs on the upper side of the counter-holding element 5, so that the upper side of the counter-holding element 5 is at least partially the thermoplastic material 4 is covered.
the counter-retaining element 5 which is partially sunk in the thermoplastic material 4, is firmly inserted in the thermoplastic material 4 and is reliably secured against falling off or slipping.
thermoplastic synthetic material 4 it is not necessary for a sink 9 to be formed around the through-opening 2 since the counter-holding element 5 is necessarily sunk into the thermoplastic synthetic material 4 in this embodiment.
the through-opening 2 can be drilled or punched into the climbing element within the through-opening 31 of the reinforcing element 3 .
