Description

[0001] Assembly shoe

[0002] The invention relates to a mounting shoe, preferably a wall shoe, for holding a safety device, preferably a safety umbrella device, comprising:

[0003] a mounting part for mounting on a building element, preferably on a wall,

[0004] a receptacle for a retaining element, in particular a crossbar, of the safety device,

[0005] a blocking part which, in a blocking position, blocks the retaining element against removal from the receptacle and, in a release position, releases the removal of the retaining element from the receptacle.

[0006] Furthermore, the invention relates to a safety system comprising:

[0007] a mounting shoe

[0008] a safety device, preferably a safety umbrella device, wherein the retaining element of the safety device is received in the receptacle of the mounting shoe.

[0009] Such a safety net is known, for example, from EP 2 550 417. In this prior art, the safety nets are mounted to the structure using a fastening device that has a U-shaped recess. The U-shaped recess is divided into two compartments by means of bolts, into which the rear frame sections of two adjacent safety nets can be inserted one above the other. The bolts reliably secure the safety net against being lifted out. However, a disadvantage is that the bolts can only be inserted from above by an operator, making assembly difficult in many applications. Furthermore, inserting the bolts is time-consuming and prone to errors.

[0010] In contrast, the object of the present invention is to alleviate or eliminate at least some disadvantages of the prior art. The invention preferably aims to create a mounting shoe and a securing system equipped with it, which is suitable for various construction applications. Preferably, the invention should enable quick, safe, and easy attachment and removal of the securing device from the mounting shoe.

[0011] This problem is solved by a mounting shoe according to claim 1 and a securing system according to claim 15. Preferred embodiments are specified in the dependent claims.

[0012] According to the invention, the mounting shoe has an actuating device with a spring element. The locking part can be moved from the locking position to the release position by means of the actuating device against the spring force of the spring element.

[0013] The mounting shoe according to the invention can be used to support a safety device. For this purpose, the mounting shoe can be mounted to the component via the mounting part. The receptacle of the mounting shoe is designed to receive a retaining element of the safety device, for example, a crossbar of a parachute system. The receptacle has an insertion opening for inserting and removing the retaining element of the safety device. In the release position, the locking element opens the insertion opening, allowing the retaining element to be inserted through the insertion opening into a receiving chamber of the receptacle. In the locking position of the locking element, however, the insertion opening is closed, thus securing the retaining element of the safety device against removal within the receptacle of the mounting shoe. Therefore, the retaining element cannot be removed from the receptacle as long as the locking element is in the locking position.The locking element preferably acts as an anti-lift device, preventing the retaining element from being lifted out of the mounting shoe when in the locked position. This ensures safe use, for example, under wind loads. To release the locking device from the mounting shoe, the locking element is moved from the locked to the released position.

[0014] In a preferred application, the building element is a wall of a structure, in particular of a building shell. In another preferred application, the building element is a scaffold.

[0015] The actuating device according to the invention has a spring element that counteracts the movement of the locking part from the locking to the release position. To release the insertion or extraction opening of the receptacle, the spring force of the spring element must be overcome. Advantageously, this significantly reduces the risk of incorrect operation. Nevertheless, operation is simpler than in the prior art, where individual locking bolts had to be set above the retaining element. Thus, the invention is characterized by operation that is both simple and safe.

[0016] If the actuating device is not engaged, the locking element automatically returns to the locking position due to the spring force of the spring element. Therefore, in use, the actuating device is operated until the retaining element is positioned in the receptacle. The actuation is then stopped, which moves the locking element into the locking position via the spring element.

[0017] In a preferred embodiment, the locking element is pivotable about a pivot axis. Thus, the transition from the locking to the release position (and vice versa) involves a pivoting of the locking element about the pivot axis. In a first embodiment, the pivot axis is fixed in position, i.e., apart from the pivoting movement, it is immovable relative to the mounting. In a second embodiment, the pivot axis is mounted on the mounting such that it is displaceable during the transition from the locking to the release position (and vice versa), preferably along a defined trajectory. This embodiment allows for a particularly compact design in confined spaces on the construction site.

[0018] For a stable and structurally simple design, the pivot axis can be formed by a bolt. In a preferred embodiment, the actuating device has a pressure actuating element for actuation, preferably from above. By pressing the pressure actuating element against the spring force of the spring element, the locking element is moved from the locked to the released position. The pressure actuating element is particularly suitable for actuation from above, for example, from a floor of a building under construction located above the mounting shoe. For this purpose, a pressure tool, for example, a rod, can be used to press down on the pressure actuating element from above, which can be moved against the spring force of the spring element so that the locking element can be moved from the locked to the released position.Depending on the design, the pressure actuating part can be moved purely translationally or perform a combined push and turn movement.

[0019] In this disclosure, the location and direction specifications, such as "above", "below", "vertical", "horizontal", refer to the intended mounting state of the mounting shoe on a vertically oriented building element, in particular on a vertical wall or scaffolding. If the mounting shoe is used in a different position, for example on a wall inclined to the vertical, the location and direction specifications must be transferred accordingly.

[0020] In a preferred design, the pressure actuating element projects upwards towards the receiver in the blocking position. This facilitates manual operation of the actuating device by a user on the construction site, for example from an upper floor.

[0021] To make manual operation of the pressure actuating part on the construction site simple and safe, the pressure actuating part is, in a preferred embodiment, displaceable downwards relative to the mounting, preferably substantially in a vertical direction downwards.

[0022] In another preferred embodiment, the actuating device has a pull-type actuating element for pull actuation, preferably from below. In this embodiment, a tensile force can be applied to the pull-type actuating element to move the blocking element against the spring force of the spring element from the blocking to the release position. By pulling on the pull-type actuating element, for example, starting from a projectile below the mounting shoe, the blocking element is moved against the spring force of the spring element from the blocking to the release position.

[0023] To simplify operation, in a preferred embodiment the pull actuation part is positioned in the blocking position opposite the receiver, preferably downwards, and in particular essentially vertically downwards.

[0024] The train actuation part is preferably displaceable downwards relative to the receiving point, preferably essentially in a vertical direction.

[0025] To achieve a compact design for the pull actuation, it is advantageous if the pull actuation element at least partially, and preferably substantially completely, penetrates the spring element. Alternatively, the pull actuation element can be arranged at least partially alongside the spring element. Furthermore, the pull actuation element can be arranged at least partially enclosing the spring element.

[0026] In a particularly preferred embodiment, the actuating device comprises a push-acting element for push actuation, preferably from above, and a pull-actuating element for pull actuation, preferably from below. This embodiment allows for particularly versatile applications, as actuation can be performed either via the push-acting element or via the pull-actuating element. Depending on the conditions on the construction site, operators can use either of the two actuating elements to move the locking element from the locked to the released position.

[0027] Preferably, the push-action and pull-action components are rigidly connected. Thus, the movement of the push-action component is transferred to the pull-action component and vice versa. In this design, the movements of the push-action and pull-action components are positively coupled.

[0028] Preferably, at least one helical spring is provided as the spring element, which is compressed by actuating the actuating device, in particular by pushing the push-actuating part and / or by pulling the pull-actuating part. After the force acting on the respective actuating part ceases, the helical spring relaxes, thereby moving the locking part back from the locking position to the release position.

[0029] In an alternative design, a tension spring is provided as the spring element, which is stretched by actuating the actuating device.

[0030] Preferably, the spring element is connected on one side to the actuating device and on the other side to the receptacle, so that spring energy is stored by the movement of the push or pull actuating part of the actuating device, which is released when the actuating is completed.

[0031] In a preferred embodiment, the receptacle has a support element for the retaining element of the locking device. In use, the retaining element is placed on the support element, so that the load is transferred by the locking device via the mounting shoe into the component. Preferably, the support element has a substantially horizontal bearing surface. The bearing surface can be flat. For example, the support element can be formed by a hollow part, in particular a shaped tube, perhaps with a substantially square cross-section.

[0032] In a preferred embodiment, the receptacle has a limiting part that projects upwards from the support part to laterally limit the retaining element. This limiting part prevents the retaining element from moving outwards, i.e., away from the component, beyond the support part.

[0033] In a preferred embodiment, the receptacle has a top-mounted insertion opening for inserting the retaining element from above. Thus, the retaining element of the locking device can be inserted into the receptacle from above via the insertion opening. For the insertion of the retaining element of the locking device, the blocking part is positioned in the release position.

[0034] In a preferred embodiment, the receptacle has a housing part on which the blocking part is movably, preferably displaceably and / or pivotably mounted about a pivot axis.

[0035] In a first preferred embodiment, the locking element is pivotable about a pivot axis that is essentially horizontal relative to the mounted operating state of the mounting shoe on the component. The pivot axis preferably runs essentially parallel to the bearing surface of the support element. Preferably, the pivot axis is displaced during the movement of the locking element from the locking to the release position and is therefore not fixed in position.

[0036] In a second preferred embodiment, the locking element is pivotable about a pivot axis that is essentially vertical with respect to the mounted operating state of the mounting shoe on the component. The pivot axis preferably runs essentially perpendicular to the bearing surface of the support element and / or essentially parallel to the longitudinal axis of the housing part. In this embodiment, the locking element is pivoted laterally to release the insertion opening. Preferably, the pivot axis is fixed in position during the movement of the locking element from the locking to the release position.

[0037] Preferably, the housing part extends upwards from the support part. In the assembled, operational state, the housing part is preferably arranged adjacent to the component. Preferably, the housing part is elongated, particularly in the vertical direction. In a preferred embodiment, the recess formed by the limiting part, the support part, and the housing part is essentially U-shaped.

[0038] For the storage of the blocking part, it is advantageous if the housing part is a hollow part, preferably a shaped tube, for example with an essentially square cross-section.

[0039] Preferably, the push-action element and / or the pull-action element is slidable along the housing part. It is advantageous if the push-action element and / or the pull-action element is slidable section by section within the housing part.

[0040] To prevent malfunctions and damage, for example due to contamination from construction work, it is advantageous if the spring element in the locked position is at least partially, and preferably completely, contained within the housing part. Furthermore, it is advantageous if the spring element is at least partially arranged within the pressure actuating part. This design is particularly advantageous if the pressure actuating part, as in a preferred embodiment, is guided essentially snugly within the housing part. If the spring element is partially contained within the pressure actuating part, the desired spring force can be provided, particularly along the length of the spring element, and at the same time the guidance of the pressure actuating part along the housing part can be improved, since the pressure actuating part can be extended according to the overlap area with the spring element.

[0041] In a preferred embodiment, a first end of the spring element is mounted on the actuating part and a second end of the spring element is mounted on the housing part. For this purpose, the actuating part can have a first spring bearing and the housing part a second spring bearing, with the spring element arranged between the first and the second spring bearing. In a preferred embodiment, the housing part has a recess facing away from the component for the passage of the locking element, wherein the locking element projects further from the recess of the housing part in the locking position than in the release position. With the transition from the locking to the release position, a locking section of the locking element, which is located outside the housing part in the locking position, is preferably displaced at least partially into the interior of the housing part, in which a bearing section of the locking element is already located in the locking position.This relocation opens the insertion opening for the retaining element of the locking device. An additional advantage is that the receptacle can be designed compactly. This is beneficial because the retaining element needs to be supported close to the component, the receptacle must have a specific receiving space for at least one retaining element, and finally, the movement of the locking element must be unimpeded.

[0042] It is particularly advantageous if the blocking part is at least partially, preferably predominantly, and especially essentially completely, retracted into the housing part in the release position.

[0043] To prevent unintentional removal of the retaining element from the receptacle, in a preferred embodiment the recess is bounded on the upper side by an upper transverse edge, which prevents the locking part from pivoting upwards in the locking position. If the locking part is subjected to an upward load in the locking position, for example by lifting the retaining element outwards, the upper transverse edge of the recess blocks the pivoting of the locking part, which can only be initiated by actuating the actuating device.

[0044] In order to accomplish the pivoting of the blocking part as reliably and structurally simply as possible when transitioning from the blocking to the release position, the recess in a preferred embodiment is limited on the underside by a lower transverse edge, which causes a pivoting of the blocking part when it transitions from the blocking to the release position.

[0045] To enable a complex movement of the locking element during the transition from the locking to the release position, the housing part has a cam guide, wherein the pivot axis of the locking element is displaceable along the cam guide. The cam guide is preferably designed such that the locking element is pivoted and moved as a whole during the transition from the locking to the release position.

[0046] In a preferred embodiment, the cam guide is formed by at least one recess, preferably on a side surface, of the housing part, wherein the pivot axis of the locking part is received in the at least one recess of the housing part. The cam guide enables reliable guidance of the pivot axis between the locking and release positions, in a manner resistant to contamination.

[0047] To ensure stable guidance of the pivot axis of the blocking part, in a preferred embodiment the housing part has two identical recesses, preferably on opposite side surfaces, which form the cam guide. The pivot axis passes through the two recesses of the housing part.

[0048] To displace the locking element downwards during its pivoting motion, the cam guide, in a preferred embodiment, features a downward section for the downward movement of the pivot axis as it transitions from the locking position to the release position. This embodiment is also characterized by a low overall height.

[0049] In a preferred embodiment, the cam track has a lateral section for the lateral movement of the pivot axis. This lateral section allows for lateral displacement in a direction deviating from the vertical. Preferably, the lateral section is designed as an entry section, which the pivot axis passes through at the beginning of the transition from the locked to the unlocked position. For a continuous transition, it is advantageous if the lateral section is curved. The curved lateral section therefore extends laterally and downwards.

[0050] Preferably, the downward section of the camber described above follows the sideways section.

[0051] In a preferred embodiment, the blocking part is moved outwards, i.e. away from the component, via the side section so far that the blocking part can be folded into the housing part along the downward section.

[0052] In order to make the housing part narrower, it is advantageous if the blocking part protrudes from an opening in the housing part, at least in the blocking position, on the inside side facing away from the receiver.

[0053] If the pivot axis of the locking element is locked against movement along the cam track in the locking position, preferably by the actuating device, the risk of malfunctions can be significantly reduced. Preferably, the pivot axis in the locking position is located at the beginning of the lateral section of the cam track.

[0054] In a preferred embodiment, the actuating device has an actuating contour which is designed to:

[0055] a) to lock the pivot axis of the blocking part in the blocking position against movement along the cam track and / or

[0056] b) to move the pivot axis of the blocking part from the side section to the downward section and / or

[0057] c) to move the pivot axis of the blocking part along the downward section of the cam track.

[0058] To ensure safety in the locked position, the actuating contour in a preferred embodiment has a locking section which blocks the pivot axis in the locked position.

[0059] In order to safely manage the transition from the lateral to the downward section, the actuation contour in a preferred embodiment has an inclined section which pushes the pivot axis from the lateral section into the downward section.

[0060] In order to reliably move the pivot axis into the end position corresponding to the release position of the blocking part, the actuating contour in a further preferred embodiment has a, preferably curved, pressure section for pressing the pivot axis along the downward section.

[0061] In a preferred embodiment, the blocking part can be pivoted to the side to release the insertion opening of the receiver.

[0062] In a preferred embodiment, the blocking part is immovably connected to the push-acting part and / or to the pull-acting part.

[0063] Preferably, the blocking part is pivotable together with the push and / or pull actuation part.

[0064] Preferably, the blocking element and the push or pull actuating element are engaged with each other, in particular via a positive locking mechanism. Furthermore, a fixed connection or a one-piece design may be provided.

[0065] Thus, the blocking part is preferably pivoted according to the push and / or pull actuation part.

[0066] To translate the displacement of the push and / or pull actuating element into the pivoting of the locking element together with the push and / or pull actuating element, a cam is preferably provided. Preferably, the cam is formed on an inner part that is immovably connected to the pull and / or push actuating element. The cam preferably interacts with a guide pin, which is preferably fixed to the receptacle. The cam is preferably shaped, in particular with a winding such that a displacement of the push and / or pull actuating element causes a rotation of the inner part, so that the locking element is simultaneously pivoted from the locking to the release position. Preferably, the inner part is shaped differently from the housing part to allow rotation of the inner part relative to the housing part.Preferably, the inner part has a substantially round cross-section, in particular a substantially circular cross-section.

[0067] The safety system according to the invention comprises a mounting shoe in one of the embodiments discussed above and a safety device, preferably a safety umbrella device, wherein the retaining element of the safety device is received in the receptacle of the mounting shoe.

[0068] The present disclosure further relates to a building system comprising:

[0069] a building shell with a building element, in particular with a wall,

[0070] a safety device in one of the above-mentioned design variants, wherein the mounting shoe is attached to the component.

[0071] A fall arrest system is preferably provided as a safety device. The fall arrest system includes a parachute that can catch falling material, tools, debris, or people. The parachute can be equipped with a safety net that, when deployed, can cover an area next to the structure.

[0072] The airborne parachute system may have a folding mechanism for deploying the parachute. This allows the parachute to be deployed and retracted as needed. For example, in adverse weather conditions such as strong winds or heavy snow loads, the parachute can be quickly and easily folded and secured. Depending on the design, the airborne parachute system may have a strut arrangement, which may include at least one vertical strut and / or at least one diagonal strut to support the parachute.

[0073] The retaining element can limit the air defense system on the side of the structure, i.e., on the inside.

[0074] The invention is further explained below with reference to an embodiment illustrated in the drawings.

[0075] Fig. 1 and Fig. 2 show a parachute device which is temporarily attached to the wall of a building under construction using mounting shoes.

[0076] Fig. 3 and Fig. 4 show the connection of the airbag to the mounting shoe.

[0077] Figures 5 to 10 show the process of mounting the airlock using the mounting shoe on the wall.

[0078] Figures 11 to 17 show details of Figures 5 to 10.

[0079] Figs. 18 to 22 show sectional views of the mounting shoe in the various positions to prepare for receiving the mounting shoe.

[0080] Figures 23 to 26 show views of another embodiment of the mounting shoe.

[0081] Figures 1 to 4 show a fall arrestor device 1, which is temporarily mounted, i.e., only during the construction phase, at the edge of a building 3, here a building under construction 4. The fall arrestor device 1 can catch falling objects, but also, if necessary, falling persons, and protect persons or objects below from falling persons or objects.

[0082] As can be seen from Figures 1 to 4, the air defense system 1 has an air defense system 5, which is provided on a longitudinal side 6 of the structure 3. In the example shown, the air defense system has a folding mechanism 7 for unfolding the first air defense system 5.

[0083] As can be seen from Figures 1 to 4, the air defense system 1 has a strut arrangement 8 with vertical struts 9 and diagonal struts 10 for supporting the air defense system 5. The vertical struts 9 run parallel to the longitudinal side 6 of the structure 3. The diagonal struts support the free edge of the air defense system 5. In addition, the air defense system 1 has a retaining element 11, here a transverse strut 12, for mounting it on the structure 3.

[0084] As can be seen in Figures 1 to 4, (at least) one mounting shoe, here a wall shoe 13, is mounted on a structural element, here a vertical wall 14, of the structure 3. In the example shown, two mounting shoes are attached to the structure 3 at a distance from each other, essentially at the same height. The wall shoe 13 has a mounting part 15, here a mounting plate, which is attached to the wall 14. In the example shown, the mounting part 15 has at least one fastening opening 16, here two fastening openings 16, which are provided with at least one mounting bolt 17, here with two mounting bolts 17, for fastening the wall shoe 13 to the wall 14. The mounting part 15 lies flat against the wall 14. The bolts are then countersunk into the wall 14 perpendicular to the main plane of the mounting part.

[0085] As can be seen in Figures 1 to 4, the wall shoe 13 has a receptacle 18 in which the crossbar 12 can be reversibly and detachably received, as will be explained in detail below. The wall shoe 13 also has a locking element 19, which is movably mounted on the receptacle 18. In a locking position (see Figure 1), the crossbar 12 is secured against removal from the receptacle 18 by means of the locking element 19. In a release position of the locking element 19 (see Figure 22), the crossbar 12 can be removed from the receptacle 18. The wall shoe 13 has an actuating device 20 with a spring element 21 (see Figures 18 to 22). The blocking part 19 can be moved from the blocking position to the release position by a user by actuating the actuating device 20.The spring element 21 opposes the movement of the locking part 19 from the locking to the release position, so that the locking part 19 is biased towards the locking position. If the actuating device 20 is not actuated, the locking part 19 returns automatically from the release to the locking position due to the stored spring force of the spring element 21. In use, therefore, the actuating device 20 is only actuated until the retaining element is positioned in the receptacle 18. If the actuating device 20 is then released, the locking part 19 moves back into the locking position automatically.

[0086] As can be seen in Figures 18 to 22, the locking element 19 is pivotable about a pivot axis formed by a pivot bolt 22. During the transition from the locking to the release position (and vice versa), the locking element 19 is pivoted about the pivot axis. As described in more detail below, the pivot bolt 22 is movably mounted on the receptacle 18, so that the pivot bolt 22 is moved along a defined path of movement during the transition from the locking to the release position (and vice versa).

[0087] As can be seen from Figs. 1 to 4 and in detail from Figs. 18 to 22, the actuating device 20 has a pressure actuating element 23, which is actuated by pressure from above. In the locked position (see Figs. 1 and 18), the pressure actuating element 23 projects upwards beyond the receptacle 18, so that the pressure actuating element 23 can be operated, for example by means of a pressure tool (see arrow 24 in Fig. 1).

[0088] 13) , is accessible . By manually actuating the pressure actuating part 23, the pressure actuating part 23 is moved vertically downwards relative to the receptacle 18.

[0089] As can be seen in Figures 1 to 4 and in detail in Figures 18 to 22, the actuating device 20 additionally has a pull-actuating element 25, which is actuated by pulling from below. By pulling on the pull-actuating element 25, the locking element 18 is moved from the locked to the released position, also against the spring force of the spring element 21. After the pull actuation is completed, the locking element 18 returns to its initial position, i.e., to the locked position. In the locked position, the pull-actuating element 25 projects downwards relative to the receptacle 18, so that the pull-actuating element 25 is accessible for operation, preferably also with an aid. By manually actuating the pull-actuating element 25, the pull-actuating element 25 is moved vertically downwards.

[0090] As can be seen from Figures 1 to 4 and in detail from Figures 18 to 22, the receptacle 18 in the example shown is essentially U-shaped. The U-shaped receptacle 18 consists of a limiting part 26, a support part 27, and a housing part 28. The support part 27 has a horizontal bearing surface designed to rest the crossbar 12 of the air defense system. The limiting part 26 projects upward from the support part 27, preventing the crossbar 12 from being displaced outwards beyond the support part 27, i.e., away from the wall. The housing part 28 is located adjacent to the wall of the building shell. The blocking part 19 is mounted on the housing part 28. The housing part 28 projects upwards from the support part 27 on the inside, i.e., on the wall side. Finally, the receptacle 18 has a [missing information - likely a specific feature or feature] on its upper side, i.e.,Opposite the support surface for the crossbar 12, an insertion opening 29 is provided, through which the crossbar 12, in the release position of the blocking part 19, can be inserted from outside the receptacle 18 into the receiving space of the receptacle 18.

[0091] As can be seen in Figures 1 to 4 and Figure 18, one end of the blocking part 19 rests on the upper side of the limiting part 26 in the blocking position, so that the insertion opening 29 is closed. The other end of the blocking part 19 is pivotably mounted about the pivot pin 22.

[0092] As can be seen in Figures 18 to 22, the pressure actuating part 23 has a first spring bearing 30 and the housing part 28 has a second spring bearing 31. One end of the spring element 21, which depending on the design may also be formed from individual coil springs connected in series, is mounted at the first spring bearing 30, and the other end of the spring element 21 is mounted at the second spring bearing 31. The spring element 21 is compressed either by pressing the pressure actuating part 23 or by pulling the pull actuating part 25, thus storing spring energy which is released after the respective actuation is completed.

[0093] The push-action part 23 and the pull-action part 25 are rigidly connected to each other. In the example shown, the pull-action part 25 completely passes through the spring element 21 and projects downwards beyond the spring element 21. At its lower end, the pull-action part 25 can have an actuating eyelet 25A (see Fig. 4) to which a pulling tool for actuation (see arrow 25B in Fig. 14) can be attached.

[0094] In the example shown, the housing part 28 is a hollow part, here a square tube, which can, for example, have a substantially square cross-section. However, a round cross-section (not shown) is also possible. The pressure actuating part 23 is guided within the housing part 28 with a virtually precise fit.

[0095] In the example shown, the housing part 28 has a recess 32 (see Fig. 3) facing away from the wall, i.e., towards the receiving space, for the passage of the locking element 19. In the locking position, the locking element 19 protrudes from the recess 32 of the housing part 28 in a substantially horizontal position. When transitioning from the locking to the release position, the locking element 19 is largely displaced into the interior of the housing part 28. This displacement releases the insertion opening for the retaining element of the locking device. In the example shown, the recess 32 is bounded on the upper side by an upper transverse edge 32A, which prevents the locking element 19 from pivoting upwards in the locking position.

[0096] In the example shown, the recess 32 is bounded by a lower transverse edge 32B, which, as will be explained in more detail below, causes the blocking part to pivot when it is transferred from the blocking to the release position.

[0097] As can be seen from Fig. 3 and Figs. 18 to 22, the housing part 28 has a cam guide 33, wherein the pivot axis of the locking part 19 is guided along the cam guide 33 during its movement from the locking to the release position (and vice versa). In the example shown, the cam guide 33 is formed by two identical recesses 34 on opposite sides of the housing part 28. The pivot bolt 22 is inserted into these recesses 34 of the housing part 28 with a virtually exact fit, so that the pivot bolt 22 is forced along the path of the recesses 34.

[0098] As can be seen in Figures 18 to 22, the cam guide 33 in the example shown consists of a curved lateral section 33A and a vertical downward section 33B. At the beginning of the movement of the locking part 19 from the locking to the release position, the lateral section 33A causes the pivot bolt 22 to move laterally outwards, i.e., away from the wall, and simultaneously downwards, before the pivot bolt 22 is moved exclusively vertically downwards along the downward section 33B. For space reasons, the housing part 28 has an opening 35 on its inner side facing away from the receptacle 18, through which the locking part 19 projects in the locking position. The blocking part 19 is moved outwards, i.e. away from the component, via the lateral section 33A at the beginning of the opening movement so far that the blocking part 19 can then be folded into the housing part 28 along the downward section 33B.

[0099] As can be seen in Figures 18 to 22, the pressure actuating element 23 has an actuating contour 36, which controls the movement of the pivot bolt 22 along the cam guide. In the example shown, the actuating contour 36 has a locking section 36A, which blocks the pivot bolt 22 in the locking position. In the example shown, the actuating contour 36 also has an inclined section 36B, which forces the pivot bolt 22 from the lateral section 33A into the downward section 33B during actuation. Finally, in the example shown, the actuating contour 36 has a pressure section 36C, which is curved here, with which the pivot bolt 22 is pushed vertically downwards along the downward section 33B until it reaches the release position.

[0100] Figures 18 to 22 show the process of unlocking the wall shoe 13.

[0101] According to Fig. 18, the blocking part 19 is arranged in the blocking position. The actuating device 20 is arranged in the upper end position, i.e., in the unactuated state. The locking section 36A of the actuating contour 36 prevents the pivot bolt 22 from being moved along the cam guide.

[0102] As shown in Fig. 19, actuation via the actuating device 20 is initiated either by pulling or pushing. The actuating device 20 has been moved downwards slightly, but the locking element 19 is still in the locking position. The inclined section 36B comes into contact with the pivot bolt 22. The spring element 21 is tensioned.

[0103] As shown in Fig. 20, the pivot bolt 22 is pressed downwards along the lateral section 33A of the cam guide as the actuating device 20 is further displaced. The locking element 19 is still in the locking position. The spring element 21 is further tensioned.

[0104] As shown in Fig. 21, the actuating device 20 is moved further downwards. The pressure section 36C of the actuating contour 36 pushes the pivot bolt 22 downwards along the downward section 33B of the cam guide. This causes the blocking part 19 to pivot. The spring element 21 is further tensioned.

[0105] According to Fig. 22, the actuating device 20 has reached its lower end position, in which the insertion opening on the upper side is released. The spring element 21 is under maximum tension. The assembly of the locking system is shown in Figs. 5 to 17.

[0106] As can be seen from Fig. 5, see also the detail in Fig. 11, boreholes are drilled in the wall 14, into which the mounting bolts 17 of the wall shoes 13 are later inserted.

[0107] As can be seen from Fig. 6, cf. also the detail in Fig. 12, the wall shoes 13 are then mounted on the wall 14. For this purpose, the fastening openings 16 of the mounting part 15 of the respective wall shoe 13 are aligned with the drill holes in the wall 14 and the mounting bolts 17 are inserted.

[0108] As can be seen in Fig. 7, the safety net 5 can then be brought into position against the structure 3, for example with a crane (not shown). According to Fig. 13, the wall shoe is moved into the release position by pushing, and according to Fig. 14 by pulling.

[0109] Fig. 8, cf. also the detail of Fig. 15, shows the insertion of the retaining element into the wall shoe 13 while the actuating device 20 is actuated. The vertical struts 9 are arranged in an oblique intermediate position.

[0110] Fig. 9, cf. also the detail of Fig. 16, shows the end position of the airlock 5. The actuating device 20 is still actuated.

[0111] Fig. 10, cf. also the detail of Fig. 17 shows the final assembly position, in which the blocking part 19 has returned to its blocking position after the actuation of the actuating device 20 has ended by relaxation of the spring element 21.

[0112] Figures 23 to 26 show views of another embodiment of the mounting shoe, with only the essential differences to the embodiment above being described below.

[0113] In this embodiment, the locking element 19 can be pivoted to the side to release the insertion opening 29 of the receptacle 18. As in the first embodiment, the transition from the locking to the release position and vice versa can be effected either by push actuation from above or by pull actuation from below. In the example shown, an inner part 37, here with a circular cross-section, is provided. The inner part 37 is rigidly connected on one side to the push actuation element 23 and on the other side to the pull actuation element 25. Furthermore, the locking element 19 is rigidly connected to the push actuation element 23, the pull actuation element 25, and the inner part 27. A stationary guide pin 38 is arranged on the housing part 28, which interacts with a cam 39 of the inner part 37.The cam 39 is designed with a winding shape, so that the downward movement of the inner part 37, caused by pressure actuation of the pressure actuation part 23 or pull actuation of the pull actuation part 25, is converted into a rotational movement of the inner part 37 and thus also of the pressure actuation part 23, the pull actuation part 25, and the locking part 19. Thus, the locking part 19 is pivoted laterally into the release position against the force of the spring element when a tensile force is applied to the pull actuation part 25 or a compressive force is applied to the pressure actuation part 23. The guide pin 38 forces the inner part 37 to rotate about its longitudinal axis, thereby releasing the locking part 19 from the locked position (see Fig. 23).

[0114] 23, Fig. 26) is pivoted into the release position (cf. Fig. 24, Fig. 25). Without tensile or compressive load, the blocking part 19 returns to the blocking position by the force of the spring element 21. In the example shown, the spring element 21 is a coil spring, which can be arranged between a spring bearing on the inner part 37 and a stationary counter bearing.
