For the sake of clarity, the same reference numerals are always used in the figures for identical or comparable components.

The FIG. 1 shows a fall arrest device 10 which is screwed onto two adjacent parallel rafters 20 and 21. The fall protection device 10 has a mounting base 30 which comprises an outer tube 40 and an inner tube 50 displaceably held in the outer tube 40. By telescoping the inner tube 50 and the outer tube 40, the length of the mounting base 30 along the longitudinal direction X of the tubes 40 and 50 can be changed, whereby an adaptation of the fall protection device 10 to different rafter distances is possible.

For fastening the mounting base 30 to the two rafters 20 and 21 fasteners in the form of angle parts 60 and 70 are available, which allow a screwing the fall protection device 10 on the rafters 20 and 21.

To connect a tubular or rod-shaped securing element 80 to the mounting base 30, holding means 90 are provided, which comprise an upper clamping element 100 and a lower counter clamping element 110. The upper clamping element 100 is connected to the lower counter-clamping element 110 by means of screw connections, which allow clamping of the mounting base 30 between the upper clamping element 100 and the lower clamping element 110 by tightening.

The FIG. 1 moreover shows a connection device 810 in the form of an eyelet, which is attached to the remote from the holding means 90 end of the securing element 80 - indirectly or directly - is attached. The connection device 810 or the eyelet make it possible to attach an external securing means, for example a hook or rope, with which a person located on the roof can secure himself from falling.

The connection device 810 may be welded or screwed to the securing element 80. In the embodiment according to FIG. 1 For example, the connection device 810 is screwed to a connection plate 820, which is welded to the securing element 80. The connecting plate 820 is preferably a threaded disk having an internally threaded bore into which a bolt portion of the connecting device 810 provided with an external thread is screwed.

The FIG. 2 shows components of the fall protection device 10 according to FIG. 1 in another illustration closer in detail. It can be seen that the clamping element 100 has two parallel end sections 101 and 102 which extend at an angle (90 ° or at least approximately 90 °) from the inside 100i of a carrier plate 105 of the clamping element 100 in the direction of the outer tube 40 of the mounting base 30. Centered between the two parallel end portions 101 and 102 is a support member 103 formed by a plate. The support element 103 or the plate extends at a right angle from the inside 100i of the clamping element 100 or from the inside of the carrier plate 105 of the clamping element 100 in the direction of the outer tube 40 and is supported on this.

The arrangement of the support element 103 is selected such that it is located below the connection section 81 of the securing element 80, so that when tightening screw connections 150 which connect the clamping element 100 to the counter-clamping element 110, the support element 103 below the connection section 81 on the Mounting base is supported and thus optimal power transmission between the clamping element 100 and the mounting base 30 in the region below the connecting portion 81 is achieved.

The clamping element 100 and the support element 103 may be sections of a one-piece component, for example a cast part or an extruded profile part. Alternatively, the support element 103 may be formed by a separate plate, which is attached to the inner side 100i of the clamping element 100 or the inside of the carrier plate 105, in particular welded.

The screw 150 have in the embodiment according to FIG. 2 Screws 151 and nuts 152; Alternatively, other types of screw are possible, for example on the basis of threaded rods or the like. In addition, the clamping element 100 and the counter-clamping element 110 can also be connected to one another by means of further components, for example by means of a pivoting joint, which allows pivoting between the clamping element 100 and the counter-clamping element 110 when mounting the two elements to the mounting base 30.

Be as in the embodiment according to FIG. 2 nuts 152 are used, it is advantageous if they are firmly attached to the clamping element 100 or counter-clamping element 110, particularly preferably - for better accessibility of the screw head of the screw 151 during assembly - on the outside of the counter-clamping element 110, in particular welded to prevent the nuts 152 from falling down during assembly and to facilitate installation of the fall arrest device 10.

Alternatively, threaded elements such as threaded bushes in the clamping element 100 or the counter-clamping element 110, particularly preferably - for better accessibility of the screw head of the screw 151 during assembly - are pressed into the counter-clamping element 110, which allow a subsequent screwing the screws 151.

It is also possible, in the clamping element 100 or counter-clamping element 110, particularly preferably - for better accessibility of the screw head of the screw 151 during assembly - in the counter-clamping element 110, cut thread and screw the screws 151 directly to the clamping element 100 or counter-clamping element 110. In the latter embodiment can be dispensed with nuts or threaded elements such as threaded bushes in an advantageous manner.

The FIG. 2 In addition, the embodiment of the counter-clamping element 110 is shown by way of example in greater detail. It can be seen two parallel end portions 111 and 112 which extend from the inner side 110i of the Gegenklemmelements 110, namely from the inside of a support plate 115 of the Gegenklemmelements 110 at a right angle in the direction mounting base 30 and supported on this. Between the two parallel end portions 111 and 112, a counter-support member 113 is arranged, which is formed by a plate. The plate or the counter-support element 113 extends perpendicularly from the inside 110i of the counter-clamping element 110 or from the inside of a carrier plate 115 of the counter-clamping element 110 in the direction of the mounting base 30 and is supported on this.

The counter-support element 113 and the support element 103 are opposite each other and aligned in the longitudinal direction of the securing element 80, so that when tightening the screw 150, the support member 103 and the counter-support member 113 locally a very high contact pressure on opposite sides below the connecting portion 81 on the mounting base 30th exercise. Due to the arrangement of the support element 103 and the counter-support element 113 below the connection section 81, a particularly high torsional strength of the securing element 80 relative to the mounting base 30 is achieved by the support element 103 and the counter-support element 113. In addition, the support member 103 and the counter support member 113 ensure that there is no sagging or Arcing the clamping element 100 and the counter clamping element 110 or the carrier plates 105 and 115 when tightening the screw 150 in the region of the connecting portion 81 comes.

The FIG. 2 In addition, the design of the angle part 60 shows in more detail. It can be seen a support portion 61, which serves for supporting the angle portion 60 on the rafter 20, and a contact portion 62, the side of the rafter 20 according to FIG. 1 is applied. For screwing on the support portion 61 and the abutment portion 62 bores are provided, can be passed through the screws. The connection of the mounting base 30 and the outer tube 40 to the angle part 60 will be discussed below in connection with the FIGS. 7 and 8 explained in detail.

The angle part 70 according to FIG. 1 can from its construction, the angle part 60 according to FIG. 2 correspond or be identical with this.

In the FIG. 2 In addition, it can be seen that the support member 103 and the counter-support member 113 are directly opposite, directly opposite to one of the two parallel end portions 101 of the clamping member 100 and one of the two parallel end portions 111 of the Gegenklemmelements 110 and the other of the two parallel end portions 102 of the clamping element 100 and the other of the two parallel end portions 112 of the Gegenklemmelements 110 directly opposite.

The FIG. 3 shows the clamping element 100 according to FIG. 2 closer in detail. The two parallel end sections 101 and 102 as well as the support element 103 arranged between the two end sections can be seen.

For connection of the connecting portion 81 of the securing element 80 (see. FIG. 2 ), the clamping element 100 has a through hole 104, which allows a pushing through of the connecting portion 81 by the upper support plate 105 of the clamping element 100. For mounting the securing element 80, the connecting portion 81 is pushed through the through hole 104 until it encounters the support element 103 located below the through hole 104. Subsequently, the terminal portion 81 is fixed in this position, for example, welded.

It is regarded as particularly advantageous if the connection section 81 is fastened, in particular welded, both on the outside 100a of the clamping element 100 and on the inside 100i of the clamping element 100. In addition, the terminal portion 81 is preferably also connected to the support member 103, for example, welded. In other words, it is thus possible to connect the connection section 81 at three interfaces, namely on the outside 100a, the inside 100i and the support element 103.

The FIG. 3 moreover, shows the configuration of the parallel end portion 101 in more detail. It can be seen a recess 200, the projections 201, for example, serrated projections has. The protrusions 201 are formed by the step shape of the recess 200.

If the end portion 101 is placed on the mounting base 30, so the projections 201 rest on the mounting base, so that it when tightening the screw 150 according to FIG. 2 comes to a pressing in of the projections 201 in the mounting base. By pressing the projections 201 into the outer tube 40 of the mounting base 30, there is a positive connection and moreover preferably to a jamming between the outer tube 40 and the inner tube 50 therein, as soon as the projections 201 deform the material of the outer tube 40 in such a way that this is pressed onto the inner tube 50.

The support member 103 and the parallel end portion 102 are provided with corresponding recesses or recesses 200 and corresponding projections 201, so that the support member 103 and the end portion 102 jamming between the outer tube 40 and the inner tube 50 when tightening the screw 150 according to FIG. 2 can effect. The recesses and projections in the support element 103 and in the parallel end section 102 are preferably aligned with those of the end section 101 in the longitudinal direction X of the mounting base 30 (cf. Fig. 1 ).

The FIG. 4 shows the clamping member 100 with the support member 103 according to FIG. 3 closer in a plan view. The through hole 104 can be seen through which the connection section 81 can be pushed in the direction of the support element 103 located below the through hole 104. In addition, bores 106 can be seen, through which the in FIG. 2 shown screws 151 of the screw 150 can be passed.

The FIG. 5 shows the clamping member 100 with the support member 103 in a view from the side. It can be seen that the support element 103 is arranged centrally between the two parallel end sections 101 and 102 of the clamping element 100.

The FIG. 6 shows the clamping member 100 with the attached support member 103 in a view from the front, as seen along the longitudinal direction X of the mounting base 30 (see. FIG. 1 ). It can be seen that the stepped recess 200 and the projections 201 of the end portion 101 are aligned with those of the end portion 102 and the support member 103. If, during assembly, the recess 200 is placed on the mounting base 30, so when tightening the screw 150 according to FIG. 2 the projections 201 of the two end portions 101 and 102 and the protrusions 201 of the support member 103 in the mounting base 30 press in and to a deformation of the outer tube 40 and lead to jamming of the outer tube 40 with the inner tube 50 therein. In order to ensure this jamming, the length of the inner tube 50 is chosen such that this is below the retaining means 90 (see. FIG. 1 ) into the outer tube 40 hineinerstreckt. The clamping element 100 and the counter clamping element 110 are preferably placed on the outer tube 40.

The FIG. 7 shows an embodiment of the angle part 60 according to FIG. 2 , It can be seen the support portion 61 and the abutment portion 62 in a view from the side.

The FIG. 8 shows the angle part 60 according to FIG. 7 in a plan view, after the outer tube 40 of the mounting base 30 according to FIG. 2 has been attached. It can be seen that the angle part 60 is provided in the interface region to the outer tube 40 with two holes 60 a, which lie within the inner contour of the outer tube 40. The function of the holes 60a is to facilitate hot-dip galvanizing of the outer tube 40 after welding the angle member 60 to the outer tube 40.

It can also be seen that the support section 61 and the contact section 62 are separated by a bending edge 63. The center axis M of the outer tube 40 attached to the angle member 60 has a distance A from the support portion 61 and the bending edge 63, which is between 0.3 times and 1.5 times, more preferably between 0.5 times and 1.0 times the depth T of the clamping element (cf. FIGS. 3 and 4 ), wherein the depth T is seen along the direction perpendicular to the longitudinal direction of the outer tube 40 of the mounting base and perpendicular to the longitudinal direction of the fuse element 80. In the case of such a dimensioning an optimal placement of the fall protection device in the roof space is achieved below the roof tiles.

The angle part 70 according to FIG. 1 is preferably identical to the angle part 60. Also, the angle part 70 thus preferably has two holes which lie within the inner contour of the inner tube 50 attached thereto. In the case of the angle part 70, it is preferably provided that the center axis of the inner tube 50 attached to the angle part 70 has a distance to the support section and the bending edge, which is between 0.3 times and 1.5 times, particularly preferably between 0 , 5 times and 1.0 times, the depth T of the clamping element (cf. FIGS. 3 and 4 ) lies.

Incidentally, the above statements apply in connection with the FIGS. 1 to 10 corresponding.

The FIG. 19 shows another embodiment of a fall protection device 10, which comprises a mounting base 30, a securing element 80 connected to the mounting base and a connection device 810 attached to the securing element 80. The connection device 810 enables a mechanical coupling with one in the FIG. 19 not shown external securing means, in particular a rope or a hook (eg snap hooks).

The mounting base 30 is as in the fall protection devices 10 according to the FIGS. 1 to 18 telescopically designed and thus adjustable in length and can be attached to one end and / or on a rafter of a roof and attached to another end and / or on an adjacent rafter of the roof, in particular screwed.

The clamping element 100 is formed in the embodiment of Figure 19 by a U-shaped in cross-section component, in particular a U-shaped cast or extruded profile part, the two parallel end portions 101 and 102 and one has two parallel end portions 101 and 102 connecting carrier plate 105. The plate plane of the support plate 105 is parallel to the longitudinal direction of the mounting base 30 and thus parallel to the longitudinal direction of the outer tube 40 and parallel to the longitudinal direction of the inner tube 50. The two end portions 101 and 102 each form an outer support wall, which is supported on the mounting base 30. Other support elements, such as those in the embodiments according to the FIGS. 1 to 18 existing support elements 103 are missing in the embodiment according to FIG. 19 ,

The embodiment of the counter-clamping element 110 corresponds to the configuration of the clamping element 100. Thus, the counter-clamping element 110 in the embodiment according to FIG. 19 by a U-shaped in cross-section member, in particular a U-shaped cast or extruded profile part, formed, the two parallel end portions 111 and 112 and the two parallel end portions 111 and 112 connecting support plate 115 has. The plate plane of the support plate 115 is parallel to the longitudinal direction of the mounting base 30 and thus parallel to the longitudinal direction of the outer tube 40 and parallel to the longitudinal direction of the inner tube 50. The two end portions 111 and 112 each form an outer support wall, which is supported on the mounting base 30. Other support elements, such as those in the embodiments according to the FIGS. 1 to 18 existing counter-supporting elements 113, missing in the embodiment according to FIG. 19 ,

The fall protection device 10 according to FIG. 19 can - apart from the differences described in terms of the design of the clamping element 100 and the Gegenklemmelements 110 - otherwise, for example, the fall protection devices according to the FIGS. 1 to 18 correspond.

The FIG. 20 shows the clamping element 100 of the fall protection device 10 according to FIG. 19 again in a different view. The counter clamping element 110 is - preferably missing Through hole 104 apart - preferably identical to the clamping element.

The FIG. 21 shows a further embodiment of a fall protection device 10. In this, the opposite end portions 101 and 102 of the clamping member 100 are interconnected by means of two longitudinal plates 850, of which in the FIG. 21 only one is recognizable. The other longitudinal plate is covered by the end portion 101 and the support plate 105.

The two longitudinal plates 850 are arranged parallel to one another and parallel to the longitudinal direction of the mounting base 30. The two longitudinal plates 850 are each perpendicular to the support plate 105 and perpendicular to the two end portions 101 and 102. The two longitudinal plates 850 are preferably connected both to the support plate 105 and with the two end portions 101 and 102, more preferably, welded.

The opposite end portions 111 and 112 of the Gegenklemmelements 110 are connected to each other by means of two longitudinal plates 851, of which in the FIG. 21 only one is recognizable. The other longitudinal plate is hidden by the end portion 111 and the mounting base 30.

The two longitudinal plates 851 are arranged parallel to one another and parallel to the longitudinal direction of the mounting base 30. The two longitudinal plates 851 are each perpendicular to the support plate 115 and perpendicular to the two end portions 111 and 112. The two longitudinal plates 851 are preferably connected both to the support plate 115 and with the two end portions 111 and 112, more preferably, welded.

The FIG. 22 shows the clamping member 100 with the two longitudinal plates 850 again in a different view.

The arrangement of the two longitudinal plates 851 in the counter-clamping element 110 is preferably identical to that in the clamping element 100, so that the FIG. 21 in other words, the arrangement of the longitudinal plates 851 in the counter-clamping element 110 shows.

The clamping element 100 and the counter-clamping element 110 consist in the embodiments according to the FIGS. 1 to 22 preferably of a different, harder material than the portion of the mounting base 30, which pinch the inner sides 101i and 110i.

In addition, the clamping element 100 and the counter-clamping element 110 and the outer tube 40 of the mounting base 30 are preferably dimensioned such that the clamped outer tube 40 is deformed on the outside by a proper tightening of the screw. The inner diameter of the outer tube 40 of the mounting base 30 and the outer diameter of the inner tube 50 of the mounting base 30 are particularly preferably coordinated such that the inner tube in the outer tube clearance, at least largely free of play, is movable and that by deforming the mounting base, the inner tube 50 (or Case of a rod as inner element of the rod) and the outer tube 40 are clamped together so that they are fixed relative to each other.

For fixing the mounting base 30 to the two rafters 20 and 21, fasteners in the form of angle members 60 and 70 - as in the FIGS. 1 to 22 shown - are used. Alternatively, T-profiles 65 can also be used-in an equally advantageous manner-as fastening elements. Such an embodiment exemplifies the FIG. 23 , It can be seen that the tubes 40 and 50 of the mounting base are preferably externally attached to the roof portion 65a of the T-profile, in particular welded.

In the case of particularly pointed roofs, it is advantageous if the two fastening elements on the mounting base 30, ie the outer element (eg outer tube) assigned to them or the inner element (eg inner tube or rod) assigned to them, in each case form a shorter one Attachment section L1 and a longer attachment portion L2 are arranged offset. Such a configuration is a simplified representation in the FIG. 24 shown. The two fasteners are T-profiles 65, however, the advantageous offset of the fasteners relative to the mounting base 30 can be provided in a corresponding manner in other fasteners such as angle parts.

The two shorter attachment portions L1 and the two longer attachment portions L2 are preferably in pairs opposite one another, viewed parallel to the tube longitudinal direction of the outer or inner tube.

In the FIG. 25 Another embodiment of a fall protection device 10 is shown after it has been mounted on a pitched roof 700. You can see rafters 710, which extend obliquely downwards or upwards at the angle of inclination of the roof and battens 720, which are bolted to the rafters 710 and transverse to the rafters and thus extend horizontally. On the roof battens roof tiles can be hung, which for reasons of clarity in the FIG. 25 not shown.

As reflected in the FIG. 25 and in which the fasteners 66 closer pointing FIG. 26 can recognize the fasteners 66 each have a support portion 66a, which extends along or against the longitudinal direction of the mounting base 30 with a predetermined first section width B1 and rests on the respective rafters 710. In addition, the fastening elements 66 each have an abutment portion 66b which extends transversely to the longitudinal direction of the mounting base, extends with a predetermined second section width B2 and rests laterally on the respective rafters 710.

The section width B1 of the support section 66a is smaller than the section width B2 of the abutment section 66b. The section widths B1 and B2 in each case relate to the longitudinal direction of a connecting edge 66c connecting the two sections, which is arranged parallel to the longitudinal direction of the rafters 710 in the installed state of the fall protection device 10. The section width B1 thus corresponds to the length of the connecting edge 66c; the section width B2 is parallel to the connection edge 66c and, accordingly, larger than the length of the connection edge 66c. Accordingly, the contact surface of the abutment portion 66b laterally on the rafter will be greater than the support surface of the support portion 66a on the rafters.

The support section 66a has a mounting option in the form of a hole 1000, with which the support section 66a can be screwed onto a rafter of a roof. The abutment portion 66b has two or more attachment options in the form of two holes 1000, with which the abutment portion 66b can be screwed laterally to the rafter.

The support portion 66a is arranged symmetrically relative to the abutment portion 66b such that the center M1 of the support portion 66a coincides with the center M2 of the abutment portion 66b. The centers in each case relate to the longitudinal direction of the connecting edge 66c.

The arrangement of the holes 1000 in the fastener 66 is, for example, symmetrical to the center of the respective sections.

In the presentation according to FIG. 25 the mounting base 30 is screwed in an intermediate region 730 between two rafters 710 and two roof battens 720a and 720b. It can be seen that the mounting base 30 is mounted such that the support portion 66a faces and preferably abuts the lower roof batten 720a (see distances A1 and A2 in FIG FIG. 25 ). Since the support section 66a rests on the rafter 710, ie on the upper side 710 'of the roof rafter 710, a further "downwards sliding" of the mounting base 30 is not possible since it has already been pushed against the lower roof lath 720a.

The abutment portion 66b abuts the rafter 710 at the side, that is, at the side surface 710 "extending perpendicularly to the upper side 710 ', and is laterally screwed thereto since the abutment portion 66b bears laterally against the rafter and, unlike the rest portion 66a, does not rest on the upper side it can not interfere with the lower roof batten 720a, but can rather be pushed along the roof rafter 710 below the lower batten 720a, so that it partially projects below the lower roof batten 720a lower roof batten 720a can be screwed to the rafter 710.

In the FIG. 27 an embodiment of a fall arrest device 10 is shown, in which the attachment point P of the mounting base 30 on the fasteners 66 with respect to the center M of the support portion 66a in the direction transverse to the longitudinal direction of the mounting base and along the y direction and thus along the rafter longitudinal direction seen - transverse offset (see offset V) is. The support portion 66a and the abutment portion 66b of the fasteners 66 are each symmetrically aligned with each other so that the centers M and M 'of the two portions 66a and 66b of each of the two attachment portions 66, respectively coincide and each have the same offset V to the mounting base 30.

In the FIG. 28 an exemplary embodiment of a fall protection device 10 is shown in which the attachment point P of the mounting base 30 on the fastening elements 66 with respect to the center M of the support portion 66a - viewed in the direction transverse to the longitudinal direction of the mounting base or along the y direction and thus along the rafter longitudinal direction - is offset (offset V). In addition, the support portion 66a and the abutment portion 66b of the fasteners 66 are each asymmetrically aligned with each other or offset to form a second offset V2, so that the center M of the support portion 66a and the center M 'of the abutment portion 66b in the two fasteners 66 fall apart.

By the second offset V2, the portion of the abutment portion 66b, which is located above the lower batten 720a, is larger than the other portion of the abutment portion 66b, which is located below the lower batten 720a.

Moreover, in the Figures 27 and 28 can be seen, the holes 1000 are arranged laterally offset from one another in the y-direction; this avoids the rafters 710 cracking or splitting when screws are tightened to secure the fall arrestor 10.

The FIG. 29 shows an embodiment of an arrangement with two or more fall protection devices, which are mounted on a roof 700 and of which in the FIG. 29 two are shown and designated by the reference numerals 10 and 11. The two fall protection devices 10 and 11 are preferably designed as exemplified above in connection with the FIGS. 1 to 28 has been explained. The fall arrest device 11 is attached to a first pair 711 of adjacent rafters 710, and the other fall arrest device 11 is attached to another pair 712 of adjacent rafters 710.

The two fall protection devices 10 and 11 are connected by means of a coupling element 830, in particular a rope, wire or wire rope, which is pulled through and / or attached to the connection devices 810, which are preferably eyelets.

In the presentation according to FIG. 29 By way of example, it is assumed that even more fall protection devices than those shown are present and the ends, in particular cable ends, 831 of the coupling element 830 are connected to further fall protection devices (not shown).

The fall protection devices 10 and 11, in particular their connection devices 810, and additionally also the coupling element 830 each allow for a mechanical coupling with an external securing means 860, preferably a (connected to a person to be secured) rope 861 and a hook 862 (z. B. snap hooks). The hook 862 is preferably hooked into the coupling element 830.

The securing means 860 is preferably hooked to the coupling element 830 such that it is displaceable along the longitudinal direction X of the coupling element 830 and allows movement of a person secured with the securing means 860 on the roof 700 along the longitudinal direction X.

In the FIG. 30 an arrangement with three fall protection devices 10, 11 and 12 is shown, of which the outer fall protection devices 10 and 12 at the same time attachment points for the ends, in particular cable ends, 831 of the coupling element 830 form; the fall protection device 11 merely serves as a middle holding element for the coupling element 830. The fall protection devices 10, 11 and 12, in particular their connection devices 810, as well as in addition the coupling element 830 in each case allow a mechanical coupling with an external securing means 860, which preferably has a cable 861 connected to a person to be secured and a hook 862 (FIG. eg carabiner hook).

The hook 862 of the securing means 860 is preferably hooked to the coupling element 830 such that the securing means 860 can be displaced along the longitudinal direction X of the coupling element 830 and allows movement of a person secured with the securing means 860 on the roof 700 along the longitudinal direction X.

In the fall protection devices 10, 11 and 12, the fastening elements 66 are each arranged offset to the mounting base 30 to allow installation even with very sharp roofs and thus high risk of falling.
