  • gratings In the industrial environment in particular, there is often a requirement to secure construction sites on gratings, for example in process technology or energy technology systems. For example, when a grating is uncovered, its surroundings must be secured against the risk of falling. Since barrier tapes or barrier chains are not permitted for this purpose, barriers are usually constructed from wood, for example from square timber and boards attached to it. The assembly and disassembly of such securing devices is labor-intensive, and there is a risk of injury to the Mon expensive from wood splinters and handling tools. In addition, the individual parts of the device can usually only be used once and must be disposed of after dismantling.
  • the object was therefore to develop known safety devices in such a way that they can also be used for other areas of application, for example gratings. Easy and quick assembly and disassembly should be possible.
  • the securing devices should also be reusable.

  • a clamping device which is connected to the foot part and which comprises a clamping means and an engagement element.
  • the base plate has at least one opening, and the tensioning means and the engagement element interact in such a way that the engagement element can be guided through the opening in the base plate to a support surface in the structure.
  • the tensioning means pulls the engagement element upwards in a vertical direction, so that the underside of the base plate is braced against the structure.
  • Another object of the invention is a quick release railing in modular design including send at least two support posts according to the invention and at least one railing strut that is releasably attached to the fastening means of the support post. Support posts and railing struts form the modules from which the quick release railing can be constructed.
  • the support post comprises a support tube, a foot part connected to it, and a tensioning device connected to the foot part.
  • the support tube can be designed in different ways.
  • the support tube is preferably designed as a straight tube with a round or angular cross section, which can be constant or variable over the length of the tube.
  • the support tube particularly preferably has a cross section that is constant over its axial length.
  • the cross section is round.
  • the cross section is designed as an octagon, hexagon or rectangle, in particular as a square.
  • the support tube can be constructed from different materials.
  • the support tube is preferably made of a metal, particularly preferably of aluminum, steel or stainless steel.
  • the foot part can be designed in different ways.
  • the foot part is preferably designed as a straight tube with a round or angular cross-section, which can be constant or variable over the length of the tube.
  • the foot part particularly preferably has a cross section that is constant over its axial length.
  • the cross-section is round.
  • the cross section is designed as an octagon, hexagon or rectangle, in particular as a square.
  • the bottom plate at the lower end of the foot part is intended to be placed with its underside on egg nem structure.
  • Typical structures for generic railings are concrete surfaces that have only slight unevenness, or gratings, especially in an industrial environment.
  • the base plate can be designed for the intended use of the support post.
  • the underside of the base plate is preferably flat in order to ensure that it stands firmly on the structure.
  • the area is the base plate with which it rests on the structure, at least twenty times, especially preferably at least thirty times larger than the cross-sectional area of the shaft of the foot part. This prevents the support post from tilting out of the perpendicular.
  • the foot part can be constructed from different materials, the shaft of the foot part and the base plate can be made of the same or different materials.
  • the foot part including the base plate is preferably made from a metal, particularly preferably from aluminum, steel or stainless steel.
  • the support post includes a tensioning device that is connected to the foot part, for example screwed or riveted.
  • the clamping device comprises a clamping means and a handle element.
  • the engagement element is intended to be guided through an opening in the base plate to a support surface in the structure.
  • the opening in the base plate is preferably located close to the shaft of the foot part. In this case, the engagement element is guided close to the foot part so that the risk of tripping due to protruding or protruding components is prevented. It is also preferred that the engagement element is adapted to the requirements that result from the structure on which the support post is to be braced.
  • the engagement element is preferably designed such that it can enclose one or more bars of the grating.
  • a design of the engagement element is particularly preferred in which the lower end of the engagement element is designed as a U-shaped hook which is suitable for encompassing one or more bars of the grating from below.
  • the tensioning means cooperates with the engagement element in such a way that the tensioning means in the tensioned state pulls the engagement element upwards in the vertical direction.
  • the clamping means can be rotatably attached to the foot part with its lower end, and the engagement element rotatably on the clamping means above its attachment to the foot part.
  • the height by which the engagement element is pulled upward in the vertical direction can be set within predetermined limits. This results in a flexible and diverse usability of the support posts, for example with gratings of different types, in which the distance between the bars and the surface varies.
  • the tensioning means and the engagement element are fastened to the foot part and to one another in such a way that the tensioning device acts as an eccentric during tensioning. This enables fast, secure and simple bracing of the support post on the structure in one work step.
  • the effect of the eccentric is understood here to mean that a rotary movement is converted into a translatory movement. It is particularly preferred to convert a rotary movement of the clamping device into a longitudinal movement of the engagement element.
  • the tensioning means is designed as a lever which, in the tensioned state, rests essentially parallel on the foot part.
  • the parallel alignment along the foot part causes the tensioning means to lie as close as possible to the foot part in the clamped state, so that the risk of tripping due to protruding parts is greatly minimized.
  • the clamping device preferably comprises a securing element, by means of which the clamping means can be fixed on the foot part.
  • the securing element can, for example, be a pawl.
  • the securing element is preferably designed as an angled pawl. The securing element prevents the clamping device from being accidentally released.
  • this has a further clamping device connected to the foot part with clamping means and engagement element, and the base plate has at least one further opening.
  • the tensioning devices and the openings in the base plate are arranged on different sides of the support post.
  • the tensioning devices and the openings in the base plate are preferably arranged on opposite sides of the support post.
  • connection between the support tube and the foot part can be fixed or variable.
  • the support tube and the foot part are firmly connected to one another, for example as a one-piece component or as two separate components that are positively, non-positively and / or materially connected to one another.
  • the foot part and the support tube are made in one piece and have a round cross section.
  • the foot part and the support tube are connected so as to be rotatable relative to one another about the axis of the support post.
  • This configuration which is more complex in comparison to the fixed connection, offers the advantage that the alignment of the railing struts is independent of the alignment of the foot parts and can therefore be freely designed. While the foot parts must follow a certain orientation depending on the structure, for example using the bars of gratings, the rotatability of the support tube also allows the balustrade to be oriented with any angular offset to the orientation due to the structure. This enables flexible and versatile use of the support posts and the quick-release railing in a modular design.
  • the rotatable connec tion comprises a component which is arranged inside the support tube and the foot part in the axis of the support post and is positively, non-positively and / or materially connected to both the support tube and the foot part .
  • the component is designed as a rod, in particular made of a solid material, to which the radially cantilevered handle elements are attached, which engage with the support tube and the foot part.
  • a handle can be fixed on the foot part and movable on the support tube, movable on the foot part and fixed on the support tube, or be designed to be movable on the foot part and the support tube.

  • the support tube can also have several fastening means, for example to accommodate several railing struts.
  • the support tube has at least one fastening means for an upper railing strut and at least one fastening means for a lower railing strut.
  • This embodiment is suitable, for example, for providing a quick-release railing which comprises a handrail as the upper railing strut and a knee strut as the lower railing strut.
  • the fastening means can be identical or different, for example with regard to their dimensions.
  • the fastening means can be identical or different, for example with regard to their dimensions.

  • the cross-sectional areas of the lower handrail strut and the fastening element assigned to it are at least 10% smaller than the cross-sectional areas of the upper handrail strut and the fastening elements assigned to it.
  • Different cross-sectional areas have the advantage that, on the one hand, the total weight of the quick-release railing can be reduced and, on the other hand, a simple distinction can be made between upper and lower railing struts during assembly of the railing.
  • this comprises at least one upper railing strut and a lower railing strut, which are connected to one another via connecting struts.
  • the advantage of this embodiment is that the upper and lower handrail struts are already firmly connected so that they do not have to be individually attached to the support tubes, which makes assembly easier.
  • the frame which is formed by the upper railing strut, lower railing strut and connecting struts, can also comprise other components, for example a network or grid, in order to secure the space between the upper and lower railing struts.
  • Both the individual railing struts and the railing connected to form a frame can have locking elements at their ends for locking the railing struts to the support tubes of the support posts.
  • the locking elements are designed as claws which, in the locked state, at least partially enclose the support tubes.
  • the locking elements are particularly preferably secured against unintentional opening, for example by snap locks on the claws.
  • the locking elements on one side of the railing struts are offset in the vertical direction relative to the locking elements on the opposite side of the railing struts.
  • the term “vertical direction” refers to the condition attached to the support tubes. This configuration makes it possible to attach two railing frames to the same support tube, since the locking elements of one railing frame are attached to the support tube at a different position than the locking elements of the other railing frame.
  • the quick release railing of this embodiment comprises at least one upper railing strut and a lower railing strut which are connected to each other via connecting struts, the railing struts having locking elements on each side for locking the railing struts to the support tubes of the support posts, the locking elements on one side of the railing struts are arranged offset in the vertical direction to the locking elements on the opposite side of the railing struts.

  • a support post as shown in Fig. 5 and 6 was carried out with the dimensions described below from aluminum.
  • the support tube 1 was made from a tube with a circular cross section, an outside diameter of 50 mm and a length of 1120 mm.
  • the lower end of the tube formed the foot part 3, which is thus integral with the support tube 1 was connected.
  • three rings each with a height of 20 mm and an outer diameter of 60 mm, were fastened with screws to the support tube 1 as fastening means 2 for upper Ge country braces .
  • the vertical distances between the three rings were each 60 mm.
  • the support tube 1 was placed with its foot part 3 vertically on a base plate 4 and welded to this.
  • a trapezoidal sheet metal was welded to the foot part 3 and to the base plate 4 on two opposite sides.
  • the base plate 4 with the dimensions 360 ⁇ 360 ⁇ 10 mm had two elongated holes of 30 ⁇ 100 mm.
  • Two locking clamps from DESTACO (model 351-R) were used as clamping devices.
  • FIG. 7 shows a view above and a plan view below of an embodiment of railing struts connected to form a frame with locking elements.
  • Both railing struts each include two partial struts, one of which has a reduced outer diameter so that it can be inserted into the interior of the other partial strut.
  • the two railing struts are telescopic and can be adjusted in any position between a minimum length and a maximum length via a fixing element 12.
  • Both railing struts have locking elements 1 1 for Verriege development of the railing struts on the support tubes 1 of the support posts at their two ends.
  • the ends of the railing struts are arranged offset via an intermediate piece in the direction of the frame interior, the upper railing strut 8 down and the un direct railing strut 9 up.
  • the locking elements 1 1 fastened on one side of the railing struts are offset in the vertical direction to the locking elements 11 on the opposite side of the railing struts.
  • the locking elements 1 1 are designed as claws that at least partially enclose the support tubes in the locked state. The locking elements are secured against unintentional opening by snap locks on the claws.
  • Railing struts connected to a frame according to FIG. 7 were made of aluminum with the dimensions described below.
  • the upper railing strut 8, the lower railing strut 9 and the connecting struts 10 were made of tubes with a circular cross section and an outer diameter of 50 mm.
  • the connecting struts 10 were welded to the railing struts.
  • the top and bottom railing struts were arranged in parallel, the vertical distance between the outer sides of the railing braces ben on one side was 630 mm and on the other side 470 mm.
  • the lengths of the partial struts of the upper and lower handrail struts were chosen so that in the retracted state a length of 1800 mm and in the extended state of 2500 mm was achieved, each measured from claw center to claw center. These dimensions correspond to the minimum length and the maximum length between which the railing struts can be telescopically adjusted.
  • a star handle 12 was provided on the upper and lower railing struts.
