DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

[0058] Identical or similar components in different figures are provided with the same reference numbers. The illustrations in the figures are schematic.

[0059] FIG. 1 and FIG. 2 show a schematic illustration of a safety device 100 for securing a person to a floor panel 151 of a shuttering system 150. In FIG. 1, safety device 100 is depicted in a release position and in FIG. 2, safety device 100 is depicted in a securing position.

[0060] Safety device 100 has a safety post 101 and a base element 102 that is attached to safety post 101. Base element 102 can be placed on the floor panel or ceiling panel 151 of shuttering system 150. Safety post 101 has a personal safety element 103 to which the person can be selectively secured. Safety device 100 also has a securing mechanism 110 with a securing carrier 117 on which at least one securing hook 111 is arranged. The securing carrier 117 is coupled to base element 102. The engagement element is designed as a securing hook in the exemplary embodiments. Securing hook 111 can be adjusted into a securing position (FIG. 2) and a release position (FIG. 1), wherein securing hook 111 can be engaged in the securing position with shuttering system 150 in order to fix base element 102 on floor panel; 151, and wherein securing hook 111 in the release position can be decoupled from shuttering system 150 in order to decouple base element 102 from floor panel 151.

[0061] Shuttering system 100 is used to create a form for pouring concrete walls and in particular concrete ceilings. Shuttering system 100 is described in FIG. 1 and FIG. 2 as a ceiling shuttering system. Shuttering system 100 here specifically has a support device 152 to which floor panels 151 can be attached. Support device 152 is thus designed in such a manner that this can be quickly and easily assembled and dismantled and can also adapt to different surface shapes. For example, shuttering system 150 is made of a support device 152 that, for example, also has crossbeams on which floor panels 151 can be placed. The crossbeams are held at a desired height via floor supports 154. Support profiles 153 are arranged between floor panels 151 on supports 154. Supports 154 are distributed with each having a defined grid dimension.

[0062] Safety post 101 is fixed to base element 102. Base element 102 is placed on floor panel 151. Base element 102 is secured to shuttering system 150 by means of securing mechanism 110 so that an overturning of safety post 101 is prevented. Safety post 101 extends from base element 102 in a vertical direction if base element 102 is placed on floor panel 151.

[0063] Safety post 101 further has a personal safety element 103, to which the person can be selectively and releasably secured. Personal safety element 103 is, for example, a loop or hook at which the installer can be secured directly or via a safety device to safety post 101. The personal safety element is specifically arranged in a rotatable manner on safety post 101.

[0064] Safety post 101, for example, has a longitudinal extension direction about which personal safety element 103 is rotatably arranged. Thus, the person that is connected to personal safety element 103 can move around post 101, wherein personal safety element 103 co-rotates. Safety post 101 has, for example, an extension length from 1 meter to 2 meters.

[0065] Securing mechanism 110 is fixed to base element 102. Securing carrier 117 of securing mechanism 110 has securing hook 111 that is engaged with and specifically hooked into shuttering system 150 at the support profile 153 described above. Hook 111 in the present exemplary embodiment can be rotationally pivoted or translationally displaced relative to securing carrier 117 in order to be adjusted between the securing position and the release position.

[0066] Securing hook 111 in the securing position is engaged with shuttering system 150 in such a manner that a secure positive and non-positive anchoring of base element 102 on floor panel 151 is generated. In particular, a gap is provided between two adjacent floor panels 151 through which securing hook 111 can protrude in order to hook into or engage with a support profile 153 present under floor panel 151.

[0067] Securing hook 111 can additionally be moved in particular into the release position, in which securing hook 111 releases the positive and non-positive connection to support profile 153 (see FIG. 1), so that safety device 100 can be displaced to a different desired place.

[0068] Securing hook 111 is pivotably mounted about a first axis of rotation (I) on securing carrier 117. Securing hook 111 can thus pivot between the securing position and the release position.

[0069] Base element 102 has a support surface 104 for resting on floor panel 151 and a securing surface 105 opposite support surface 104 to which safety post 101 is attached. Securing carrier 117 is arranged on support surface 104.

[0070] Support surface 104 is located in a support plane that is designed parallel to a surface plane of floor panel 151. Securing surface 105 is configured opposite support surface 104. Securing surface 105 is located in an attachment plane that is designed parallel to support surface 104 and is correspondingly distanced from it.

[0071] Securing carrier 117, which is arranged on support surface 104, projects out from support surface 104 in the opposite direction from securing surface 105. Therefore, if the support surface lies atop securing panel 151, securing carrier 117 projects through at the edge of a panel 151, so that securing hook 111 can engage with a support profile 153 of support device 152 of shuttering system 150 arranged under floor panel 151.

[0072] Securing mechanism 110 further has a coupling lever 113 that is rotatably mounted on safety post 101 about a second axis of rotation II and is rotatably mounted on engaging hook 111 about a third axis of rotation III that is configured at a distance from first axis of rotation I in such a manner that it can be rotated by turning coupling lever 113 about the second axis of rotation II of engaging hook 111.

[0073] Coupling lever 113 is in particular rotatably mounted on safety post 101 or base element 102 and runs along securing surface 105. Securing hook 111 has a coupling area that runs from securing carrier 117 through base element 102 and projects from securing surface 104. Coupling lever 113 or transfer lever 118 is rotatably coupled onto this coupling area about a third axis of rotation III.

[0074] A pivoting of securing hook 111 can thus be controlled via an induced pivoting of the coupling lever because third axis of rotation III is arranged at a distance from first axis of rotation I about which securing hook 111 rotates relative to securing carrier 117.

[0075] Third axis of rotation III is in particular parallel to first axis of rotation I and is arranged at a specific radius or distance from it.

[0076] Coupling lever 113 is mechanically actuated via a tension element 114 or a tie rod 114. Tie rod 114 extends, for example, from coupling lever 113 along safety post 101. This allows securing hook 111 to be operated at an operating position which is at a distance from coupling lever 113 and thus from base element 102. It is therefore not necessary for the installer to move the securing hook 111 between the release position and the securing position in a bent position. This ensures an ergonomically advantageous safety device that can be conveniently operated.

[0077] By use of the control rod 114, a bidirectional force transfer can be implemented. Control rod 114 can in particular be rotatably arranged about an additional axis of rotation on coupling lever 113, wherein the additional axis of rotation is designed at a distance from third axis of rotation III and second axis of rotation II.

[0078] Securing mechanism 110 also has a sliding element 115 that is arranged in such a manner that it can be displaced along safety post 101 in the direction of base element 102. Control rod 114 is attached to sliding element 115.

[0079] Sliding element 115 thus forms, for example, a sleeve that encloses safety post 101 over all or part of its circumference. A simple and robust control option is thus created for safety device 100 because tensioning element 114 is translatorily guided and cannot be freely moved on safety post 101. The sleeve has, for example, a bore through which a safety bolt 116 can be inserted transverse to the direction of movement of the sleeve along safety post 101 in order to secure the sleeve or sliding element 115 against undesired displacement. A release or actuation of sliding element 115 thus requires two different movement sequences: a) the removal of safety bolt 116 and b) the displacement of sliding element 115 along safety post 101. This increases the security against an undesired actuation of sliding element 115. Securing bolt 116 can further be secured by means of a locking system (e.g. with a padlock) in order to prevent an undesired release of securing bolt 116.

[0080] Securing mechanism 110 has an additional securing hook 112 that is fixed to securing carrier 117 in such a manner that additional securing hook 112 can be coupled to shuttering system 150, wherein securing hook 111 is arranged at a distance relative to additional securing hook 112 in such a manner that a distance between securing hook 111 and additional securing hook 112 can be adjusted by a pivoting of securing hook 111 relative to additional securing hook 112. In this manner, by pivoting securing hook 111, shuttering system 150, and in particular support profile 153, are clamped between securing hook 111 and additional securing hook 112 in the securing position. This offers an easily adjustable and safe fixing of safety device 100 to shuttering system 150.

[0081] FIG. 3 shows an enlarged view of securing mechanism 110 in release position from FIG. 1 and FIG. 4 shows an enlarged view of securing mechanism 110 in securing position from FIG. 2. The preferred embodiments of securing mechanism 110 having securing hook 111, coupling lever 113 and transfer lever 118 are more precisely described below.

[0082] Transfer lever 118 is rotatably mounted on coupling lever 113 about a fourth axis of rotation IV and has third axis of rotation III at a distance from fourth axis of rotation IV. Transfer lever 118 forms a kind of intermediate lever between coupling lever 113 and securing hook 111.

[0083] During pivoting of coupling lever 113, transfer lever 118 is pulled along and then securing hook 111 rotates about first axis of rotation I. Second axis of rotation II, third axis of rotation III and fourth axis of rotation IV are in particular arranged at a distance from securing surface 105. Second axis of rotation II, third axis of rotation III and fourth axis of rotation IV are further arranged parallel to each other.

[0084] Coupling lever 113, transfer lever 118 and the securing hook are designed and arranged with respect to each other in such a manner that second axis of rotation II and third axis of rotation III are located on a common connector line 401 (and fourth axis of rotation IV is located below connector line 401, meaning between the connector line and securing surface 105), so that a rotation of securing hook (111) about first axis of rotation I (under action of a force on the securing hook 111 in the opening direction) is blocked. If second axis of rotation II, third axis of rotation III and fourth axis of rotation IV are located on a common connector line 401, wherein connector line 401 runs specifically orthogonally with respect to the respective axes of rotation II, III, IV, a rotation of the securing hook 401 about first axis of rotation I thus causes a tangential force on third axis of rotation III because of the pivoting of securing hook 111 and correspondingly runs along connector line 401. In particular, because connector line 401 connects second, third and fourth axes of rotation II, III, IV, the induced tangential force forms a radial force that affects the corresponding axis of rotation without resulting in a tangential force relative to the axes of rotation. In this manner, a pivoting of coupling lever 113, of transfer lever 118 and, correspondingly, of securing hook 111 is suppressed.

[0085] Insofar as coupling element 113 is not actively pivoted by tensioning element 114, no pivoting of the same can be created starting from securing hook 111 and in line with coupling rod 114 and transfer lever 118. In this manner, a structural checking member of securing hook 111 is provided so that it cannot be inadvertently pivoted from the securing position into the release position.

[0086] FIG. 5 shows a perspective representation of safety device 100 from FIG. 1 to FIG. 4. Base element 102 can further be designed as a round or square plate in order to ensure sufficient standing stability. In other words, base element 202 can be designed as a pressure plate in order to absorb a homogeneous distribution of pressure and hold a momentum in the case of a fall by an installer.

[0087] Sliding element 115 has a grip area 501, specifically a grab handle, for grasping and operating the sliding element 115.

[0088] FIG. 6 shows a perspective representation of safety device 100 that is arranged on floor panels 151 of a shuttering system 150. The support profiles 153 have so-called console heads into which crossmembers (transverse struts) are inserted, on which, in turn floor panels 151 are placed. Support profiles 153 are thus specifically designed in such a manner that securing hook 111 engages or hooks into safety device 100. The support profile is, for example, a square hollow profile. In particular, a gap is provided between two adjacent floor panels 151 through which securing hook 111 can protrude in order to hook into or engage with a support profile 153 present under floor panel 151.

[0089] The installer can travel on floor panel 151. Floor panels 151 simultaneously serve as part of the form for the concrete. After the concrete cures, floor panels 151 can be dismantled in a simple manner.

[0090] For securing the installers during the mounting of floor panels 151, safety device 100 is releasably fixed at the desired point of shuttering device 150 in order to thus protect the installer from a fall from the shuttering system 150.

[0091] Additionally, it should be noted that terms such as comprising, and the like do not preclude other elements or steps, and terms such as a or one do not preclude a plurality. Furthermore, it should be noted that features or steps that have been described with reference to one of the above embodiments may also be used in combination with other features or steps of other embodiments described above. Reference characters in the claims are not to be interpreted as being limiting.
