Description

The invention relates to a covering unit, in particular a scaffold covering unit, preferably a scaffolding floor, with at least one lift-off protection fastened in a front end region of the covering unit, which is formed with a securing pivoted lever, which is manually, preferably without tools, in the position of use of the covering unit, preferably vertical pivot axis. in particular rotation axis, from an open position in which the covering unit on a horizontal support, in particular a bolt, preferably a cross bar, for example a scaffold tube, can be placed or lifted off, in a closing or Abhebesicherungsstellung is pivotally, and vice versa, in which the Pad unit, when placed on the support, is secured against lifting from the carrier, wherein the securing pivot lever at least in its closing or Abhebesicherungsstellung means of a resilient latching element is secured to form a positive locking against unintentional pivoting about the pivot axis in a first engagement position, and wherein the securing pivot lever has a from the pivot axis in a first direction transversely, preferably vertically extending away first lever arm and a second lever arm, the extending transversely from the pivot axis in a second direction, preferably perpendicular, in particular in an opposite direction, and wherein the resilient locking element is formed with a relative to the second lever arm movable and spaced from the pivot axis arranged pressure piece.

The invention also relates to a method for securing a pad unit against lifting of a carrier according to claim 13 and to a method for unlocking a pad unit secured against being lifted off a carrier according to claim 14.

Padding units are often used in the field of scaffolding, stairs, podiums, grandstands or similar supporting structures or space structures. The padding units are usually placed on horizontal supports, in particular bolts, preferably crossbars, for example scaffold tubes, which are preferably round tubes or U-profiles, or suspended there by means of suspension aids. The pad units must be secured against lifting or taking off, as an unintentional, in particular caused by wind forces, lifting can lead to serious accidents and injuries.

To secure pad units you have in the past unit a variety of different auxiliary structures used. Among them are such constructions in which in the front end of the padding units manually, preferably tool-free, actuatable securing elements about an opening position in the pad unit vertical pivot axis of an open position in which the pad unit can be lifted or placed, are pivotable in a Abhubsicherungsstellung in which the Securing elements, the horizontal support, respectively scaffolding tubes, engage under.

Such a construction is for example from the DE 198 38 625 A1 known. There, a safety lever with the aid of this encompassing securing tab on the vertical end face of a scaffold floor between the locking tab and the vertical end face of the scaffold floor manually, preferably tool-free, rotatably clamped. The safety lever is angled both at its upper end, as well as at its lower end in approximately equal directions. In the Abhebesicherungsstellung overlap both the angled upper end of the safety lever and the angled lower end of the safety lever the scaffolding tube. In this way, a lift-off is realized.

Another construction of the copyright holder herself has become known from practice. In this case, a thin, elongated sheet metal strip is riveted to a lower horizontal wall of a front end profile designed as a cross cap in the use position of a scaffolding floor. The metal strip can be rotated manually, preferably without tools, by 360 degrees about the mediated by the rivet vertical axis of rotation, so that the metal strip can be rotated inter alia in an open position, in which the scaffolding floor provided with hooks lifted from a scaffold tube or can be hung or suspended there, are pivoted in a Abhubsicherungsstellung in which the metal strip engages under resting on the scaffold tube or there scaffolding floor, the scaffolding tube, so that then the scaffold floor against lifting is secured.

Common to both designs is the disadvantage that the safety lever, at least initially, heavy, possibly only with the aid of a tool, such as a hammer, can be rotated. In the course of use, so after repeated actuation of the safety lever, it may over time to loosen the clamping of the respective safety lever to a free rotation of the same, whereby the respective safety lever can then be easily rotated manually without the use of a tool However, it then leads to accidental release of the safety lever, d. H. to an unintentional pivoting of the same can come from the Abhubsicherungsstellung in a Abhub- or open position, so that then the scaffold floor is no longer secured against lifting. This represents a significant safety risk. In addition, in both constructions during installation and removal of the scaffolding floor to obstructions due to over time to easy rotation of the safety lever come.

From the JP 2001 254 512 A is known a scaffold floor with access opening, which can be closed by means of a pivotable about hinges tilt lid. The tilting lid can be secured against lifting by means of a spring-loaded pivoting lever.

There, a hole is formed in a lower leg of a stirnendseitig provided on a platform U-profile, through which a connecting bolt extends therethrough. The connecting pin is connected at its protruding from the lower leg out one end fixedly connected to a rigid locking lever and is at its side facing away from the other end, which is located in a spanned by the U-shaped interior, firmly connected to a hexagonal head. Between the hexagonal head and the lower leg, a compression spring is clamped, through which the connecting bolt extends. The spring can be pressed together by pressure actuation of the hexagonal head by means of a finger or by means of a suitable tool. When the spring is pressed together, the connecting bolt in the hole can be tilted away from the base end wall of the U-profile, whereby the locking lever from a locking position in which it engages under a ribbing of a side frame, by rotating about the longitudinal axis of the connecting bolt in an opening position can be pivoted, in which the platform can be mounted or dismounted. This construction is manually difficult to operate, with the risk of pinching or injury of the fingers. Also, it can come in this construction to jamming, which makes it difficult to manually open or even impossible.

This enables advantageous stacking ratios of similar or identical covering units to be stacked on one another. The securing pivot lever 26 has a bore 72 through which the rivet 61 is inserted through in the assembled state. In order to facilitate the pivoting of the securing pivot lever 26 about its pivot axis 27, a washer 67 is arranged between the securing pivot lever 26 and the lower wall 47. This may preferably consist of plastic, in particular of polyamide. The washer 67 has a through hole through which the rivet 61 is also inserted therethrough. The rivet 61 has two rivet heads 71.1 and 71.2. The first rivet head 71.1 is formed here flat and engages over the safety pivot lever 26. The here in cross section semicircular second rivet head 71.2 engages over the bore wall of the projected into the bottom wall 47 through hole. The rivet 61 is made with its rivet heads 71.1 and 71.2 in such a way that the distance between the two rivet heads 71.1 and 71.2 is slightly greater than the sum of the amounts of the thickness of the bottom wall 47, the thickness of the washer 67 and the thickness of the fuse In this way it is achieved that the rivet 61 is substantially free or even freely rotatably connected to the bottom wall 47 of the cross-linking cap 43 and secured thereto. In this way, from the beginning, ie at any time, a particularly easy pivoting or rotatability of the securing pivot lever 26 to ensure its pivot or rotation axis 27, so that the backup pivot lever always manually and without any tool would be required for its pivot axis 27 can be pivoted.

The securing pivot lever 26 is preferably made of cast metal, in particular zinc die-cast, temper or cast steel.

The securing pivot lever 26 comprises two lever arms 37.1 and 37.2. The first lever arm 37.1 acting as a safety arm extends, starting from the pivot axis 27 of the securing pivot lever 26, in a first direction 36.1 and the second lever arm 37.2 acting as a latch arm extends from the pivot axis 27 of the securing pivot lever 26 into a second one Direction 36.2, and here opposite to the first direction 36.1.

The fastening position of the securing pivot lever 26 on the lower wall 47 and the length of the first lever arm 37. 1 of the securing pivot lever 26 acting as the securing arm are designed to be coordinated with one another such that the securing pivot lever 26 is in its closing or lifting-off position 31 (FIG. FIGS. 1 to 3 ) engages below the carrier 30 designed here as a round scaffolding tube to beyond the center axis.

In the region of the free end 39 of acting as a latching arm second lever arm 37.2 of the fuse pivot lever 26 designed as a blind hole 56 is provided. In this is a cup-shaped hollow body 52, here by pressing, attached. The here cylindrical inner walls of the hollow body 52 define a cavity 53, in which a compression spring 49 and designed as a ball 51 pressure piece 50 are added. In this case, the compression spring 49 is supported at one end on the bottom of the hollow body 52, while at the other end is supported on the pressure piece 50 and the ball 51. In order to avoid that the ball 51 and the compression spring 49 can fall out of the hollow body 52, this is designed like a cage. For this purpose, the hollow body 52 has a cavity 53 partially overlapping over-grip part 54. The overlapping part 54 has an opening 68, the opening diameter 69 is smaller than the outer diameter 70 of the ball 51. In this way, therefore, the ball 51 and also on this inside supporting compression spring 49 does not fall out of the hollow body 52. The compression spring 49 is designed with its spring travel such that it presses the ball 51 under the exertion of compressive forces 55 against the overlapping part 54, so that the ball 51 acted upon by the spring force of the spring 59 protrudes by a certain amount on the overlapping part 54 to the outside if it is not hindered by external limitations or forces.

The compression spring 49 and the ball acting as a pressure piece 50 51 are part of a resilient latching element 35 and form a resilient locking element 35. This serves to the safety pivot lever 26 both in its closing or Abhebesicherungsstellung 31 (FIGS. FIGS. 1 to 3 ) as well as in its opposite about 90 degrees about the pivot axis 27 pivoted open position by positive, but releasable locking against inadvertent pivoting about its pivot axis 27 to secure such that pivoting of the backup pivot lever 26 about its pivot axis 27 both of the Closing or Abhebesicherungsstellung 31 in the open position 28 and from the open position 28 in the closing or Abhebesicherungsstellung 31 only under application of an increased pivoting force is possible. The height of the pivoting force is determined inter alia by the spring characteristic of the spring 49 and by the shape of the pressure piece 50 and the shape of the openings or holes or holes 40.1 and 40.2, which are provided here on or in the bottom wall 47 of the cross connection cap 43 , In particular in FIG. 6 It can be seen that in the latching position shown there, which acts as a pressure piece 50 ball 51 is engaged in the opening 40. The shape of the opening 40 and the two openings 40.1 and 40.2 and their arrangement is particularly from the FIGS. 3 and 4 out. Each opening 40.1 and 40.2 is designed here as a slot 45.1 or 45.2. Their longitudinal axes 46.1, 46.2 each extend perpendicular to the pivot axis 27 of the securing pivot lever 26 and intersect the pivot axis 27 respectively. The slots 45.1 and 45.2 are each spaced from the pivot axis 27 and also spaced from each other and relative to the pivot axis 27 offset by a circumferential angle 44 to each other, which is about 90 degrees here. In this way, therefore, a securing engagement position 32 can be specified through the opening 40.1, in which the resilient latching element 35, respectively acting as a pressure piece 50, spring-mounted ball 51 there can positively engage or can be latched.

In contrast, through the second opening 40.2 or through the second slot 45.2, the longitudinal axis 46.2 is arranged approximately perpendicular to the longitudinal axis 46.1 of the first elongated hole 45.1, set an opening-Einraststellung 29 be, in which then, when the fuse pivot lever 26 is pivoted into its open position 28 or has been given away, the resilient latching element 35, respectively acting as a pressure piece 50, spring-loaded ball 51 in the second opening 40.2 can positively engage or then it is locked there.

In the region of its first lever arm 37.1 acting as a safety arm, the securing pivoted lever 26 has a stop body 64 in the form of a nose. The latter extends perpendicular to the longitudinal axis 34 of the securing pivot lever 26 and parallel to its pivot axis 27. In the assembled state and in the use position 22 of the pad unit 20, the stop body 64 extends in the vertical direction. In this case, the stop body 64 projects beyond the underside 77 of the securing pivot lever 26 by a length such that it overlaps the front vertical front transverse wall 59 of the cross connection cap 43 in the installed state of the securing pivot lever 26, so that the stop body 64 can be brought to abutment there ( see in particular the FIGS. 3 to 5 ). The stop body 64 itself comprises both a first stop 62.1 and a second stop 62.2 for the securing pivot lever 26. The first stop 62.1 serves to pivot the securing pivot lever 26 about its pivot axis 27 in a first pivoting direction 63.1 (FIG. FIG. 4 ) of one or the open position 28 in the closing or Abhebesicherungsstellung 31, further pivoting of the securing pivot lever in this first pivoting direction 63.1 on the closing or Abhebesicherungsstellung 31 addition, in particular in a further open position, to prevent by in this Position of the first stop 62.1 the vertical front transverse wall 59 of the cross connection cap 43 abuts.

In contrast, the second stopper 62.2 serves to pivot the securing pivoting lever 26 about its pivot axis 27 in a second pivoting direction 63.2, opposite to the first pivoting direction 63.1, from the closing or lifting-off position 31 into or the open position 28 to prevent further pivoting of the securing pivot lever 26 beyond the open position 28 in this second pivoting direction 63.2. This is due to the fact that the second stop 62.2 then likewise abuts against the vertical end transverse wall 59 of the transverse connection cap 43, but elsewhere.

The common stop body 64 is arranged with its first stop 62.1 and with its second stop 62.2 on the securing pivot lever 26 and the latter is arranged and mounted on the cross connection cap 43 such that the securing pivot lever 26 by a pivot angle 65 from here about a maximum 90 degrees about its pivot axis 27 is pivotable or can be given away. In this way, the stop body 64 limits with its two stops 62.1 and 62.2 via the two latching positions predetermined by the openings 40.1 and 40.2, ie the opening latching position 29 and the safety latching position 32, the pivoting path of the securing pivot lever 26 about its pivot axis 27. In this way it is ensured that the securing pivot lever 26 always only within the two stops 62.1 and 62.2 of the stopper body 64 in connection with the vertical end transverse wall 59 of the cross connection cap 43 and the mounting or fastening of the securing pivot lever 26th itself defined limits about its pivot axis 27 is pivotable and thus can be located exclusively in an open position 28 or in a closing or Abhebesicherungsstellung 31 or possibly located between these two positions intermediate position. An operator can already see from afar whether the securing pivot lever is in one of its two end positions, ie either in its open position 28 or in its closing or Abhebesicherungsstellung 31 or even in an intermediate position. A position of the backup pivot lever in such an intermediate position can be effectively avoided by the following measures: Due to the effect with the resilient latching element 35 two end detent positions, ie the opening-Einraststellung 29 on the one hand and the fuse-Einraststellung 32 on the other hand and due a clearly audible to the operator at the time of engagement in these two end-latching positions can ultimately be ensured by an operator that the safety pivot lever is pivoted in any case in one of the two end-locking positions. In addition to the clear, because about 90 degrees from each other different two end-Einrastpositionen, ie the open position 28 on the one hand and the closing or Abhebesicherungsstellung 31 on the other hand, can by a suitable contrasting color of the fuse pivot lever 26 in addition even better recognition of the respective Secured position can be ensured so that it is therefore widely recognized whether the padding units 20 are provided with their provided at both ends, acting as Abhebesicherungen 25 backup pivoting levers 26 secured against lifting or not.

The fuse pivot lever 26 is designed clockwise or arrow-shaped. Its securing arm 37.1 tapers towards its tip or towards its free end 38. The latter is designed to avoid injury rounded. In the open position 28, in which the securing pivot lever 26 is latched in its opening engagement position 28, the longitudinal axis 38 of the securing pivot lever 26 extends approximately perpendicular to the central longitudinal axis 74 of the covering unit 20.

In addition, the securing pivot lever 26 is viewed in its open position 28 in a view from above of the pad unit 20, except for its stop body 64 covered by the horizontal bottom wall 47 of the transverse reinforcement cap 43. In other words, viewed in a view from above onto the covering unit 20, of the securing lever 26 in the open position 28, only the stop body 64 projects beyond the vertical end transverse wall 59 of the cross-linking cap 43. The securing arm 37.1 of the securing pivot lever 26 extends in its open position 28 in a direction approximately perpendicularly away from the center longitudinal axis 74 of the covering unit 20 to the outside.

In contrast, the securing arm 37.1 of the securing pivot lever 26 extends in its opposite the open position 28 by approximately 90 degrees, here counterclockwise, pivoted closing or Abhebesicherungsstellung 31, in which it is locked in the locking engagement position 32, approximately parallel to the longitudinal center axis 74 of the covering unit 20 and projects in a view from above onto the covering unit 20, viewed beyond the vertical end transverse wall 59 of the cross-linking cap 43.

• Ausgehend von einer Öffnungsstellung, in welcher die Belageinheit 20 auf den horizontalen Träger 30 auflegbar ist, vorzugsweise ausgehend von der Öffnungsstellung 28, in welcher der Sicherungs-Schwenkhebel 26 in der Öffnungs-Einraststellung 29 durch formschlüssiges Einrasten der als Druckstück 50 fungierenden Kugel 51 in der als Langloch 45.2 gestalteten Öffnung 40.2 der Unterwand 47 eingerastet ist (vgl. Figur 4), wird zunächst die Belageinheit 20 mit seinen Einhängehaken 66.1 und 66.2 auf den horizontalen Träger, hier das als Rundrohr gestaltete Gerüstrohr 30 aufgelegt. Es versteht sich, dass Entsprechendes auch für den im Bereich des anderen Stirnendes der Belageinheit 20 vorgesehenen zweiten, in den Figuren nicht gezeigten, Sicherungs-Schwenkhebel und für die ggf. dort vorgesehenen weiteren beiden Einhängehaken gelten kann, die auf einen weiteren horizontalen Träger, bei dem es sich ebenfalls um ein als Rundrohr gestaltetes Gerüstrohr handeln kann, aufgelegt werden können.

For the purpose of securing the pad unit 20, one can proceed as follows:

• Starting from an open position in which the covering unit 20 can be placed on the horizontal support 30, preferably starting from the open position 28, in which the securing pivot lever 26 in the opening-engaged position 29 by positive engagement of acting as a pressure piece 50 ball 51 in the designed as a slot 45.2 opening 40.2 of the bottom wall 47 is engaged (see. FIG. 4 ), the pad unit 20 is first placed with its hooks 66.1 and 66.2 on the horizontal support, here designed as a round tube scaffolding tube 30. It is understood that the same can also apply to the provided in the other front end of the pad unit 20 second, not shown in the figures, fuse pivot lever and possibly provided there further two hooks on a further horizontal support, in which may also be a scaffolding tube designed as a round tube can be placed.

Starting from this open position 28 or of these open positions, the safety pivot lever 26, or the safety pivot lever, by its manual and here tool-free pivoting about its vertical position in the use position 22 of the pad unit 20 pivot axis or axis of rotation 27 of the open position in pivoted his or her closing or Abhebesicherungsstellung 31, in which the or the fuse pivot lever 26 is latched in his or her fuse latching position 32 or are, in which acting as a pressure piece 50 ball 51 acted upon by the Compression spring 49 in the designed as a slot 45.1 opening 40.1 in the bottom wall 47 of the cross connection cap 43 positively engages or is engaged. In this securing latching position 32, the securing pivot lever 26 can only be moved from its closing or lifting-off position 31 into an open position or into the open position 28 in the direction of the inward position by applying an increased pivoting force FIG. 3 shown arrow 63.2 be swung back. A pivoting of the securing pivot lever 26 from its closing or Abhebesicherungsstellung 31 in the opposite direction 63.1 is due to the stop member 64 formed with the stop 62.1 not or in the thereby predetermined narrow limits at most slightly possible.

• Ausgehend von der bzw. den Schließ- bzw. Abhebesicherungsstellung/en 31 des bzw. der Sicherungs-Schwenkhebel 26, in welcher die Belageinheit 20 gegen Abheben von dem Träger 30 unter Ausbildung der mittels des federelastischen Rastelements 35, hier durch Einrasten der durch die Druckfeder 49 beaufschlagten und als Druckstück 50 fungierenden Kugel 51 in der als Langloch 45.1 gestalteten Öffnung 40.1 in der Unterwand 47 der Querverbindungskappe 43 bewirkten formschlüssigen Verrastung, wird der bzw. werden die Sicherungs-Schwenkhebel 26 manuell und hier werkzeugfrei unter Aufbringung einer erhöhten Schwenkkraft, beispielsweise in Richtung des in Figur 3 gezeigten Pfeils 63.2, aus der Schließ- bzw. Abhebesicherungsstellung 31 in eine Öffnungsstellung verschwenkt. Im Zuge dessen erfolgt ein Entriegeln des federelastischen Rastelements 35 hier derart, dass die Kugel 51 entgegen der Federkraft der Druckfeder 49 in den Hohlraum 53 des Hohlkörpers 52 zurück gedrückt wird, und zwar bis in eine Stellung, wie sie beispielsweise in Figur 7 gezeigt ist. In dieser Stellung liegt die Kugel 51 beaufschlagt durch die Federkraft der Druckfeder 49 an der Oberfläche der Unterwand 47 der Querverbindungskappe 43 unter Druck anliegt. Im Zuge eines Weiterverschwenkens des Sicherungs-Schwenkhebels 26 weiter in Richtung des Pfeils 63.2 gleitet die Kugel 51 in etwa auf einem Kreisbogen um die Schwenkachse 27 des Sicherungs-Schwenkhebels 26. Zum Zwecke einer Entsicherung der Belageinheit 20 wird der Sicherungs-Schwenkhebel 26 so lange weiter in der Schwenkrichtung 63.2 weiter verschwenkt, bis eine Öffnungsstellung erreicht ist, in welcher die Belageinheit 20 von dem jeweiligen Träger 30 abhebbar ist. Vorzugsweise wird der Sicherungs-Schwenkhebel 26 ausgehend von seiner Schließ- bzw. Abhebesicherungsstellung 31 so lange in der Verschwenkrichtung 63.2 um seine Schwenkachse 27 weiter verschwenkt, bis ein formschlüssiges Verrasten durch das federelastische Rastelement 35 in der Öffnungsstellung 28 erreicht wird, in welcher also die Kugel 51 beaufschlagt durch die Federkraft der Druckfeder 49 in die als Langloch 45.2 gestaltete zweite Öffnung 40.2 in der Unterwand 47 der Querverbindungskappe 43 formschlüssig einrastet bzw. eingerastet ist. Denn dann kann es beim Abheben der Belageinheit 20 von dem jeweiligen Träger 30 bzw. bei einem erneuten Auflegen der Belageinheit 20 auf dem jeweiligen Träger 30 nicht zu Störungen bzw. Kollisionen bedingt durch den jeweiligen Sicherungs-Schwenkhebel 26 kommen, weil dieser im Wesentlichen vollständig, d. h. hier mit Ausnahme seines jeweiligen Anschlagkörpers 64, unter die Unterwand 47 geschwenkt ist, also im Wesentlichen nicht in eine Richtung über die Unterwand 47 bzw. die Stirnquerwand 49 der Querverbindungskappe 43 vorsteht, in welcher sich die jeweiligen Einhängehaken 66.1, 66.2 von dieser Stirnquerwand 59 nach außen weg erstrecken.

Unlocking the covering unit 20 secured by means of the securing pivoting lever 26 of the securing pivoted lever against lifting of the horizontal support (s) 30 is described below:

• Starting from the closing or Abhebesicherungsstellung / en 31 of the fuse or the pivoting lever 26, in which the covering unit 20 against lifting of the support 30 to form the means of the resilient locking element 35, here by snapping the by the compression spring 49 acting and acting as a pressure piece 50 ball 51 in the designed as a slot 45.1 opening 40.1 in the bottom wall 47 of the cross connection cap 43 caused positive locking, the or are the safety pivot lever 26 and here tool-free application of increased pivoting force, for example in Direction of in FIG. 3 shown arrow 63.2, from the closing or Abhebesicherungsstellung 31 in an open position pivoted. In the course of this unlocking of the resilient latching element 35 takes place here in such a way that the ball 51 is pressed against the spring force of the compression spring 49 back into the cavity 53 of the hollow body 52, to a position such as in FIG. 7 is shown. In this position, the ball 51 is acted upon by the spring force of the compression spring 49 bears against the surface of the bottom wall 47 of the cross connection cap 43 under pressure. In the course of further pivoting of the securing pivot lever 26 further in the direction of the arrow 63.2, the ball 51 slides approximately on a circular arc around the pivot axis 27 of the securing pivot lever 26. For the purpose of arming the lining unit 20 of the fuse pivot lever 26 continues so long in the pivoting direction 63.2 further pivoted until an open position is reached, in which the covering unit 20 can be lifted from the respective carrier 30. Preferably, the securing pivot lever 26 is pivoted so far from its closing or Abhebesicherungsstellung 31 in the pivoting 63.2 about its pivot axis 27 until a positive locking is achieved by the resilient locking element 35 in the open position 28, in which therefore the ball 51 acted upon by the spring force of the compression spring 49 in the designed as a slot 45.2 second opening 40.2 in the bottom wall 47 of the cross connection cap 43 positively engages or is engaged. Because then, when the pad unit 20 is lifted off the respective carrier 30 or when the pad unit 20 is placed again on the respective carrier 30, interference or collisions due to the respective safety pivoted lever 26 can not occur. ie here except for its respective stop body 64, pivoted under the bottom wall 47 is, that is substantially not projecting in one direction over the bottom wall 47 and the front transverse wall 49 of the cross connection cap 43 in which the respective suspension hooks 66.1, 66.2 extend away from this front transverse wall 59 to the outside.
