Description Technical field The invention relates to a holding device for a person and snow protection system which is designed for mounting on a sloping roof of a building, in particular for mounting in the eaves area of a sloping roof, the holding device comprising: a) a base part for fastening the Holding device on a pitched roof, preferably on a roof structure and / or on a substructure of a roof installation, the base part in particular an end to be aligned on the ridge side on a pitched roof, an end to be aligned on the eaves side on a pitched roof and a support plane for placing the base part on the roof structure and / or the substructure includes, and b) a support leg which protrudes from the base part and has at least one first holder for one or more snow guard elements. Furthermore, the invention relates to a set of parts for a person and snow safety system and a person and snow safety system mounted on a roof. Another aspect of the invention relates to the use of a holding device or a set of parts for as a snow protection system and / or for securing people on a roof of a building.
PRIOR ART Roofs are constructions which close the rooms of a building underneath and protect them from the sun and the weather. The areas of the roof that are visible from the outside are called roof areas, the boundary and common cutting lines of the roof areas being referred to as roof edges. The ridge is the top and usually horizontal cut edge of two roof surfaces, while the bottom and also mostly horizontal edge of a roof surface is called the eaves. The roof structure is the supporting structure of the roof.
In the eaves area of a roof, a gutter or gutter is usually attached, which collects and drains the rainwater running off the roof surfaces.
In regions with regular snowfall, roofs also have eaves, and for longer roofs also on the roof surface itself, a snow guard or snow protection system, which prevents snow from slipping or prevents roof avalanches. Known snow guard systems which are installed in the eaves area exist e.g. made of snow guard elements in the form of snow guard grids, snow guard beams or snow guard tubes, which are attached to the roof structure with suitable brackets. So-called snow catch hooks can also be installed on the roof surfaces, which prevent the snow from sliding off. In combination with a snow guard system in the eaves area, the snow guard hooks reduce the load on the snow guard system.
Due to the risk of falling, work on roof areas is one of the particularly dangerous activities for workers. This is particularly the case for maintenance work that has to be carried out frequently and in bad weather conditions, or for troubleshooting on pitched roofs, such as when clearing gutter and drainage blockages or removing snow.
It is therefore essential that workers can secure themselves in a suitable manner for roof work. In many countries, fall protection measures are already legally required. In Switzerland, for example, when working on and on roofs from a fall height of 3 m, measures must be taken to prevent a fall.
As safety measures, for example, fixed hooks are known on the roof. These serve as attachment points at which workers can secure themselves with the aid of an attachment or safety rope.
DE 20 2006 009 225 111 (Wilhelm Flender GmbH & Co. KG,) describes, for example, a roof hook made of a sheet metal or steel body that is bent several times, which is formed as an integral stamped part from a single piece of sheet metal. The hook is suitable both as a safety roof hook and for holding grids, logs, pipes, etc. A rope for a safety device can be attached in a transverse recess of the support leg.
DE 10 2015 104 643 A1 (Otto Lehmann GmbH) discloses special, brick-shaped roof covering elements with associated support structures, which make it possible to fasten holding and bracket elements on the roof. For example, snow guard beams, snow guard grids or standing boards can be attached to the holding and console elements. It is also possible that the holding and console element is formed by a roof hook which can be loaded in the direction of the eaves and in the direction of the ridge and has at least one opening for personal security. This can be done, for example, by hanging a snap hook with a safety rope attached to it.
A disadvantage of known safety hooks, however, is that they only provide individual attachment points. In order to avoid a dangerous pendulum movement in the event of a fall, the worker may only move out of the fall line to a limited extent. The radius of action in the direction along the eaves is thus severely restricted.
If the worker has to move along the eaves during the work on the roof, as is typically the case with gutter cleaning, the safety rope must therefore be transferred from one safety hook to the next.
CH 714 866 A2
However, it must be ensured that there is always a backup. Although this is possible, it may be necessary. a variety of complicated and time-consuming reassignment processes, which pose a risk of incorrect manipulation that should not be underestimated.
Also known for attaching safety ropes are, for example, fixed ropes mounted on the roof ridge. With such fixed ropes, the disadvantages of safety hooks can be partially overcome, since they allow greater freedom of movement without having to hang the safety rope in the eaves direction. The disadvantage here, however, is that additional fastening devices have to be attached to the roof in order to install the fixed ropes, which is complex and can strongly influence the appearance of the roof. In addition, safety ropes are expediently attached to the roof ridge, which means that relatively long safety ropes are necessary when working in the eaves area of the roof. This is particularly problematic near the verge or in the area of the lateral end of the roof area, since the secured person can fall over the verge despite the safety device and start to oscillate.
There is therefore still a need for improved security systems which avoid the disadvantages mentioned above as far as possible.
DESCRIPTION OF THE INVENTION The object of the invention is to provide a security system belonging to the technical field mentioned at the outset and corresponding components which enable reliable and, in practice, simple to implement personal security on a sloping roof of a building. This is particularly true in the eaves area of the roof. In addition, the security system should be as easy to install and / or retrofit as possible, with the appearance of existing roofs being changed as little as possible.
The solution to the problem is defined by the features of claim 1. According to the invention, the support leg in particular additionally comprises at least one second holder, which is designed for fastening a linear stop device of a personal security system.
As has been found, particularly advantageous security systems can be realized with the holding device according to the invention, which enable both personal and snow security. Due to the fact that the holding device includes both a first holder and a second holder, the holding device can also be used to fasten one or more snow guard elements and to fasten a linear stop device of a personal security system running parallel to the eaves, e.g. a fixed rope and / or a safety rail can be used. This results in a compact design and enables easier installation on the roof, since only one holding device has to be installed for each of the two security systems. The appearance of the roof is also changed far less than with conventional systems.
Due to the first holder for one or more snow guard elements, the holding device according to the invention is particularly suitable for mounting in the eaves area of a roof, since snow guard systems are usually arranged in this area. Known personal security systems, on the other hand, are usually installed above the eaves area and above the snow security system.
By integrating a second bracket for a linear stop device according to the invention, it is also possible to implement a personal security system which allows greater freedom of movement in one direction along the eaves and without the person to be secured moving in parallel to the eaves at several , individual anchor points must secure.
If the holding device according to the invention is mounted in the eaves area, this enables particularly expedient securing when working in the eaves area, for example in the removal of gutter and drainage blockages. Since the linear stop device with the holding device according to the invention can in this case be arranged parallel to the eaves, it is possible that the person to be secured is secured to the linear stop device with a relatively short safety rope, which greatly reduces the risk of dangerous pendulum movements in the event of a fall ,
On the other hand, it can be avoided that the safety rope must be guided over the snow securing system when working on the gutter, as is the case, for example, with securing hooks arranged above snow securing systems or fixed ropes arranged on the roof gable. Accordingly, the risk of snagging or damage to the snow guard elements by the safety rope is greatly reduced.
The holding device according to the invention can also be installed in addition and / or instead of conventional holding devices for snow guard elements, such as snow guard tubes or snow guard grids. This provides a relatively simple option for retrofitting existing snow guard systems.
As a result, the solution according to the invention thus enables the implementation of particularly advantageous personal and snow protection systems, which are particularly suitable in connection with the work to be carried out frequently in the eaves area.
The holding device is designed in particular so that when it is mounted on a pitched roof, a linear stop device of a personal security system in one direction along the second bracket
CH 714 866 A2 of the eaves can be fastened and preferably also snow guard elements running in the direction of the eaves can be fastened to the first holder.
In the present context, the term “linear stop device” stands in particular for a permanently mounted device on which, after assembly, personal protective equipment of a person to be secured can be struck and moved at least in sections along a longitudinal axis of the stop device. The linear stop device serves in particular as a linear guide, e.g. for a safety rope. In particular, the linear stop device has a length which is at least 10 times, in particular at least 50 times, as large as a diameter or a thickness of the linear stop device. The linear stop device is particularly preferably a fixed rope and / or a securing rail. A fixed rope is particularly preferred.
The term “fixed rope” is used in the present case to refer in particular to a rope which is provided for permanent attachment to the holding device. In contrast, a «safety rope», which serves as a connection between the person to be secured and the stop on the roof, is only used for a short time during work on the roof. Typically, the fixed rope is a rope comprising or consisting of stranded metal wires, in particular steel wires, preferably stainless steel wires. Optionally, non-metallic fibers, inlays and / or coatings can also be present on the fixed rope. The fixed rope has a diameter of 3-25 mm, in particular 5-15 mm or 6-12 mm. A length of the fixed rope can e.g. 1-50 m, in particular 2-20 m, preferably 3-15 m. A safety rope is in particular a non-metallic rope, e.g. made of synthetic fibers. The safety rope is typically more flexible than the fixed rope.
A "safety rail" can e.g. are in the form of a round bar, a tube and / or a profile strip. For example, hollow profile strips with a T or H-shaped cross section are suitable. On such profiles e.g. suitably designed runners are movable in the longitudinal direction. The securing rail has, for example, a diameter or a thickness of 3-25 mm, in particular 5-15 mm or 6-12 mm. A length of the safety rail can e.g. 1-50 m, in particular 2-20 m, preferably 3-15 m. In particular, it is a metallic securing rail or a securing rail which consists of at least 50% by weight or entirely of metal. Suitable metals are, for example, aluminum and / or steel, in particular stainless steel.
In principle, however, other securing rails can also be used.
The base part of the holding device includes, in particular, an end to be aligned on a sloping roof on the ridge side and an end to be aligned on a sloping roof on the eaves side. Furthermore, the base part advantageously has a support level for placing the base part on the roof structure. The second holder enables in particular the mounting of a linear stop device in a direction of a normal to an orthogonal plane which is perpendicular to the support plane and intersects the end to be aligned on the ridge side and the end of the base part to be aligned on the eaves side.
The holding device is in particular designed such that the second holder can be loaded in a direction parallel to a straight line which runs through the end to be aligned on the ridge side and through the end to be aligned on the eaves side. At the same time, the holding device is in particular designed such that it can be loaded on the second holder in a direction of a normal to an orthogonal plane which is perpendicular to the support plane and intersects the end to be aligned on the ridge side and the end of the base part to be aligned on the eaves side.
“Resilient” means in the present case that after mounting on a roof structure, the holding device can withstand a static single load acting on the second holder in the respective direction of> 1 kN, preferably> 5 kN, more preferably> 10 kN.
The holding device is in particular designed such that it can be loaded on the second holder both in the first eaves direction (falling line) and in a direction perpendicular thereto and parallel to the roof surface or in the direction along the eaves. The holding device is particularly preferably designed such that it can be loaded in all directions on the second holder. This means in particular that the holding device or the second holder for absorbing tensile forces that are both in the direction of a fall line (ridge eaves direction), against the fall direction (ridge eaves direction) as well as perpendicular to it and parallel to the roof surface (parallel to the eaves).
In particular, the holding device meets the requirements for safety roof hooks according to chapters 7.2 and 8.1 of the standard SN EN 517: 2006 analogously, if the second bracket is used as an attachment point. The holding device also very particularly preferably also meets the requirements according to chapters 7.3 and 8.2 of the standard SN EN 517: 2006 if the second holder is used as an attachment point.
The base part and the support leg are preferably arranged so that they form an angular and / or hook-shaped structure. In particular, the base part and the support leg are arranged in such a way that they form an essentially V-shaped, U-shaped or L-shaped structure. A substantially V-shaped structure is particularly preferred. Such holding devices have proven to be particularly suitable, since these shapes enable a compact and robust construction and have good accessibility at the respective locations for assembly. In principle, other shapes are also possible. In particular, the holding device overall has an angular and / or hook-shaped structure.
CH 714 866 A2 [0034] The support leg is preferably attached to the base part in the region of one end of the base part. The support leg preferably projects at least in sections, in particular continuously, in one direction at an angle from the base part. The support leg is in particular at an angle different from 90 °, preferably at an angle of 10-80 ° from the base part. The angle specifications relate in particular to the contact surface of the holding device.
The end of the base part, to which the support leg is attached, is in particular the end of the base part to be attached to the eaves on the roof, while the opposite end of the base part is the end of the base part to be attached on the ridge side.
In particular, the support leg is inclined and / or curved toward a free end of the base part and / or towards the end of the base part to be attached on the ridge side.
The support leg is particularly preferably arranged on the base part and / or projects from it in such a way that the support leg and base part form an angular and / or hook-shaped structure. An angular structure is preferred.
According to an advantageous embodiment, the support leg is integrally connected to the base part, in particular welded, or the support leg and the base part are integrally formed. This is a particularly stable and durable holding device with a clearly defined structure.
In principle, however, it is also possible for the support leg and base part to be connected by a positive and / or non-positive connection. This, for example, in addition to or instead of a material connection. This allows e.g. Combine different base parts with different support legs, which enables targeted adaptation to the respective application or roof situation.
A positive and / or non-positive connection can in particular be designed so that an angle between the support leg and the base part is adjustable. The holding device can thus be flexibly adapted to different roof pitches, for example.
The base part is preferably an elongated, strip-like component and / or the base part is essentially band-shaped. In the present case, “band-shaped” means in particular that a length of the part under consideration, as here e.g. of the base part is larger than its width and a thickness of the part under consideration is smaller than its width. The length is preferably at least twice the width and the width is at least four times the thickness. The base part is particularly preferably a rectangular profile and / or a flat bar. Such shaped base parts have on the one hand a good support level for stable fastening of the holding device to a roof structure and / or a substructure of a roof installation and on the other hand they offer a stable base for the support leg.
In principle, however, differently designed base parts can also be suitable.
The support leg preferably comprises a straight and / or curved band-shaped part or consists of it. “Straight-line” here means in particular that a longitudinal axis of the support leg is a straight line. For example, the support leg comprises a rectangular profile and / or a flat bar. In a preferred embodiment, the support leg is e.g. substantially rectilinear along a longitudinal axis, e.g. a flat rectangular profile and / or a flat flat bar. This is particularly interesting from a manufacturing point of view and results in high stability.
But it can also be advantageous if the support leg is partially or completely curved along its longitudinal axis. The support leg can e.g. in particular as a rectangular profile curved along a longitudinal axis and / or flat bar curved along a longitudinal axis. With such a shape, additional functions can be implemented on the holding device, for example, and / or the optics of the holding device can be specifically adapted.
For example, the longitudinal axis of the support leg in a region of the free end of the support leg can run essentially parallel to a longitudinal axis of the base part. When mounting on a roof, the free end of the support leg then runs in particular parallel to the roof surface, which can be optically advantageous and / or by means of which a hook-shaped functional structure can be realized.
A plane of a largest side surface of a band-shaped support leg is in particular plane-parallel to the orthogonal plane, which is perpendicular to the support plane and intersects the end to be aligned on the ridge side and the end of the base part to be aligned on the eaves side.
Furthermore, it can be advantageous if a cross-sectional area of the support leg decreases and / or increases at least in sections in a direction from the base part to a free end of the support leg. In particular, the cross-sectional area can increase in a first section and decrease in a second section. In addition, there may be a section with a constant cross-sectional area, for example between the first and the second section. This further section can e.g. serve to attach the second bracket or the second bracket can be attached in this area.
It can also be advantageous if a width of the support leg decreases in sections and / or increases from the base part to the free end of the support leg. In particular, the width can increase in a first section and decrease in a second section. In particular, the width can increase in a first section and decrease in a second section. In addition, there may be a section with a constant width, for example
CH 714 866 A2 points between the first and the second section. This further section can e.g. serve to attach the second bracket or the second bracket can be attached in this area.
With such support legs, a particularly stable structure can be obtained in the region of the transition from the base part to the support leg, while material can be saved in the area of the support leg that is not subjected to loads.
Preferably, a plane of a largest side surface of a band-shaped base part and / or the support plane is substantially perpendicular to a plane of a largest side surface of a band-shaped support leg.
Furthermore, it can be advantageous if the support leg is supported on the base part by means of a strut. In an advantageous embodiment, the strut runs from a central region of the support leg to the base part, preferably in such a way that a free passage limited by the support leg, the base part and the strut is present between the support leg and the base part. The free passage is particularly limited by a triangular contour. With such struts, the stability of the holding device can be greatly increased, whereby high load capacities are possible even with smaller material cross sections. In principle, however, it is also possible to dispense with dying and to ensure stability in another way.
The strut is preferably integrally connected to the support leg and / or the base part, in particular welded, or the strut, the support leg and / or the base part are integrally formed. According to a special embodiment, the dying is welded to the support leg and the base part or the strut, the support leg and the base part are formed in one piece. As a result, particularly safe and durable holding devices are available. However, it is also possible to connect the dying to the support leg and / or the base part via a positive and / or non-positive connection. The holding device can also be designed such that the strut can be attached to at least two different positions on the base part and / or at least two different positions on the support leg. This allows the angle between the support leg and the base part to be adjusted in the case of a positive and / or non-positive connection between the support leg and the base part with a strut.
[0053] According to a preferred embodiment, the strut, if present, is a band-shaped part, preferably with a straight longitudinal axis and / or a rectangular profile. A plane of a largest side surface of a band-shaped base part is preferably substantially perpendicular to a plane of a largest side surface of a band-shaped strut.
The holding device can basically consist of any material suitable for the application. The holding device or individual parts thereof can also be made of different materials. The holding device can e.g. comprise metallic materials, plastics, fiber composite materials and / or composite materials or the holding device consists of them. Steel and / or fiber-reinforced plastic, such as e.g. carbon fiber reinforced plastic (CFRP) and / or glass fiber reinforced plastic.
In a preferred embodiment, the first holder for one or more snow guard elements is designed in the form of one or more, in particular two, openings, preferably bores, in the support leg. This allows, for example, common snow guard elements, such as Attach snow guard tubes or snow guard to the holding device in a simple but safe meadow. However, other first holders for the snow guard elements can also be used. For example, Grooves, clamps and / or hooks.
The second holder is preferably arranged in an area facing away from the end of the base part to be aligned on the ridge side and / or in an area facing away from the free end of the base part on the support leg. The linear stop device can thus be attached to the holding device from the outside, which is advantageous in terms of assembly technology. In addition, with such an arrangement, the linear stop device can be attached to the roof below the snow guard elements, so that the snow guard elements do not interfere with personal security in the eaves area.
The second holder preferably includes a contact surface for the linear stop device and / or a connecting element for fastening the linear stop device. The contact surface is preferably formed at least at an intended contact area with that of the linear stop device and / or the connecting element for fastening the linear stop device as a flat surface, in particular as a round, square or rectangular surface.
A surface normal of the contact surface, in particular in the intended contact area, lies in particular in the orthogonal plane, which is perpendicular to the support plane of the base part and intersects the end to be aligned on the ridge side and the end of the base part to be aligned on the eaves side. The surface normal of the contact surface preferably points away from the end of the base part to be aligned on the ridge side.
In a substantially angular or hook-shaped holding device, the surface normal of the contact surface is in other words preferably in a plane spanned by the free end of the base part, the free end of the support leg and the fastening region of the support leg on the base part. The surface normal of the contact surface preferably points away from the free end of the base part and / or from the end to be aligned on the ridge side.
The surface normal of the contact surface preferably does not run parallel, in particular perpendicular, to a normal to the orthogonal plane, which is perpendicular to the support plane of the base part and intersects the end to be aligned on the ridge side and the end of the base part to be aligned on the eaves side.
CH 714 866 A2 In a further preferred embodiment, the surface normal of the contact surface is perpendicular to a longitudinal axis of the support leg.
With the contact surfaces as described above, the linear stop device and / or connecting element for attachment can place the linear stop devices in a predefined orientation and along the eaves direction on the second holder, which greatly simplifies stable and secure attachment. This applies in particular if the linear stop device is a fixed rope and / or a safety rail. In principle, the second holder can also be designed differently.
The second holder is in particular designed in such a way that the linear stop device of a personal security system can be fastened to the holding device without passage through an annular and / or closed region. This greatly simplifies the assembly or the exchange of holding devices.
The second holder advantageously has connecting means for the positive and / or non-positive fastening of a linear stop device and / or a connecting element for fastening the linear stop device. Elements of screw connections, snap-in connections, snap connections, tongue and groove connections, for example, come into consideration as connecting means. These are preferably detachable connections. Accordingly, the connecting means can e.g. be selected from the group consisting of recesses, bores, projections, pins, screw threads, internal threads, external threads, tongues, grooves, snap hooks, snap hooks and / or clamps.
[0065] The second holder particularly preferably has one or more bores, preferably with an internal thread. The bores extend in particular in a direction which lies in the orthogonal plane, which is perpendicular to the support plane of the base part and intersects the end to be aligned on the ridge side and the end of the base part to be aligned on the eaves side. The linear stop device and / or a connecting element for fastening the linear stop device can thus be fastened to the second holder or to the holding device.
In principle, however, other elements for fastening the linear stop device and / or the connecting elements for fastening the linear stop device can also be provided.
The second holder preferably includes a base, the base protruding and / or protruding in particular from the support leg. The abovementioned contact surface is preferably implemented on the base, in particular on an area of the base facing away from the end of the base part to be aligned on the ridge side.
The base or a free end of the base projects in particular in a direction of a normal to the orthogonal plane, which is perpendicular to the support plane of the base part and intersects the end to be aligned on the ridge side and the end of the base part to be aligned on the eaves side, away from the supporting leg. In this case too, the contact surface is preferably present on an area of the base facing away from the end of the base part to be aligned on the ridge side.
Preferably, the base is an integral part of the support leg or support leg and base are integrally formed. This allows relatively inconspicuous but nevertheless resilient bases to be realized with little material expenditure.
The base can be designed, for example, as an angled area of the support leg.
According to a further advantageous embodiment, the base is a separate component which can be fastened to the support leg by a positive and / or non-positive connection, in particular the base can be aligned with respect to the support leg. This can increase flexibility, since individually adapted and / or adjusted bases can be used.
In a further advantageous embodiment, there is at least one projection in the region of the end to be aligned on the ridge side or at a free end of the base part. In particular, the projection is designed as an angled region of the base part, preferably as an approximately angled region.
[0073] Particularly preferably, there is a step-like course of the base part in the region of the end to be aligned on the ridge side or at the free end of the base part.
By means of projections or step-like courses, the base part can partially or completely encompass elements of the roof structure and / or elements of a substructure of a roof installation during assembly on the roof, which improves the stability.
Furthermore, the base part preferably has recesses and / or bores which make it possible for the holding device to be fastened to the roof structure and / or the substructure in a positive and / or non-positive manner, in particular by means of screws.
A further aspect of the present invention relates to a set of parts for a person and snow protection system, which is designed for mounting on a roof of a building, in particular on a sloping roof, comprising:
a) at least one holding device as described in one of the preceding claims and
CH 714 866 A2
b) at least one linear stop device of a personal safety system, preferably a fixed rope and / or a safety rail.
Such a set of parts can e.g. can be used to retrofit an existing snow guard system on a roof, especially a pitched roof.
The set of parts preferably comprises two, three, four, five, six or more holding devices.
In particular, the set of parts also includes at least one fastening means for attaching the linear stop device to the second holder of the at least one holding device. In particular, there is at least one fastening means for each holding device contained in the parts set.
[0080] The at least one fastening means comprises, for example, an end termination and / or an intermediate holder for the linear stop device. For example, the at least one fastening means can include a cable end termination and / or a cable intermediate holder. For example, also be a fitting, a sleeve, a thimble, an eyelet and / or a clamp. The at least one fastening means is in particular matched to a connecting means on the second holder.
The set of parts and / or the at least one fastening means advantageously have at least one connecting element by means of which the fastening means can be fastened to the second holder of the holding device, optionally using a third element. The at least one connecting element can be an integral part of the fastening means or can be present as a separate part.
For example, the connecting element can be a screw, a bolt, a split, a hook, a latching hook and / or a clamp.
Preferably, the fastening means and / or the connecting element is designed such that it can be brought into positive and / or non-positive contact with the second holder, in particular with a connecting means present there.
The linear stop device, e.g. attach a fixed rope and / or a safety rail directly to the second holder of the at least one holding device.
In particular, the set of parts contains at least one intermediate holder, in particular an intermediate cable holder, with which a region of the linear stop device can be fastened to a holding device between the two ends of the linear stop device, for example at the cable ends, optionally using a connecting element. This means that a continuous, linear stop device, in particular a continuous safety cable, can be realized on a roof and held by several holding devices. This is especially the case if the parts set has more than two, e.g. three, four, five or six holding devices.
According to a preferred embodiment, the intermediate holder comprises a cable intermediate holder with a sleeve open on both sides, which can be pushed over a fixed rope, and wherein the sleeve has a support device or a spacer in a jacket area, which can be fastened to the second holder of the holding device. The support device or one of the spacers are in particular at least in one section thinner than a diameter of the fixed rope.
According to a further advantageous embodiment, the set of parts comprises a runner movable along the linear stop device, in particular along the fixed rope, the runner preferably having a stop point for attaching a safety device, e.g. a safety rope and / or snap hook. It is preferably a slider and / or a roller runner. With runners of this type, the person to be secured can move, for example, along the eaves on the roof.
In principle, this can also be achieved by directly hanging a snap hook on the linear stop device. However, this leads to premature wear of the stop device and is less convenient.
If both a rotor and an intermediate holder are present, the intermediate holder is in particular designed such that the intermediate holder can be run over with the rotor in the assembled state. In particular, the runner only partially surrounds the linear stop device in the assembled state. The person to be secured or the runner can thus also be moved along the entire length of the linear stop devices in the case of multi-supported linear stop devices.
Furthermore, the set of parts can comprise a rope tensioner, with which a tension of a fixed rope can be adjusted in the assembled state. Another part of the parts set can e.g. be a fall absorber, which allows controlled extension of the fixed rope in the event of a fall. This can minimize the burden on the falling person.
In particular, in the set of parts, at least one fastening means, in particular an end closure, is attached to the linear stop device, e.g. mounted on the fixed rope. The assembly effort can be reduced and the safety increased by such an at least partial assembly. The individual parts of the subset can

WAYS OF IMPLEMENTING THE INVENTION FIG. 1 shows a side view of a holding device 10 according to the invention which, for example, consists entirely of stainless steel.
The holding device 10 has a band-shaped base part 11 with a rectangular profile or a rectangular cross section and a longitudinal axis 11.4. The side surface of the rectangular profile lying at the bottom in FIG. 1 forms a support plane 11.3. with which the base part 11 can be placed on a roof structure. The length of the base part 10 can e.g. about 15 cm long, while a width for example about 3 cm and a thickness e.g. is about 5 mm. In the region of an end 11. 1 of the base part 11 to be aligned on the upstream side, a rectilinear support leg 12 is attached. The support leg 12 consists of a band-shaped rectangular profile, which has two bevelled corners, so that a hexagonal shape is formed in the top view in FIG. 1. Correspondingly, the cross-sectional area of the support leg 12 increases along the longitudinal axis 12.3 in a first region, is constant in the central region and then decreases again towards the free end 12.2.
The support leg 12 projects obliquely from the base part 11, so that the base part 11 and the support leg form a substantially V-shaped structure. The support leg 12 is welded to the eaves-side end 11.1 of the base part 11 with its lower end 12.1 in FIG. 1, which is opposite its free end 12.2.
The free end 12.2 of the support leg 12 is inclined toward the ridge side to be aligned or the free end 11.2 of the base part 11. The longitudinal axis 11.3 of the base part 11 and the longitudinal axis 12.3 of the support leg 12.3 have an angle of approximately 60 °, for example.
The support plane 11.3, which forms a plane of a largest side surface of the band-shaped base part 11, is essentially perpendicular to a plane of a largest side surface of the band-shaped support leg 12 (see also the front view in FIG. 2).
In the area of the end 11.2 of the base part to be aligned on the ridge side, this has a step-shaped projection or a step-like course 16. The step-like course 16 allows the base part 11 to mount elements of the roof structure such as the battens and / or during assembly on the roof Partly grasp the counter battens. In order to fasten the holding device 10 according to the invention, the base part 11 has several through bores 17.1, 17.2, 17.3 in the region of the end 11.2 to be aligned on the ridge side, which enable the holding device 10 to be fastened to a roof structure, for example with screws (not shown).
CH 714 866 A2 A strut 13 extends from a central area of the base part 11 from the top of the base part 11 or from the side opposite the support plane 11.3 to a central area of the support leg 12. The strut 13 is also designed as a band-shaped part with a rectangular profile. The plane of a largest side surface of the band-shaped strut 13 is essentially perpendicular to the support plane 11.3 of the band-shaped base part 11. The support leg 12 is supported on the base part 11 with the aid of the strut 13.
In the area of the lower end 12.1 of the support leg 12, a first and through hole 14.1 is made in the support leg 12 above the base part 11, while in the area of the free end 12.2 a second through hole 14.2 is made in the support leg 12. The two bores 14.1, 14.2 form a first holder for one or more snow guard elements.
In the area facing away from the free end 11.2 of the base part 11, a base 15 is also attached to the support leg 12 at a medium height. The base 15 forms a second holder for fastening a linear stop device or a fixed rope of a personal security system. The base 15 is substantially perpendicular from the front edge of the support leg 12 in a direction of a normal to the orthogonal plane, which is perpendicular to the support plane 11.3 of the base part 11 and intersects the end 11.2 to be aligned on the ridge side and the end 11.1 of the base part 11 to be aligned on the eaves side Support leg 12 away.
An approximately square contact surface 15.1 for a linear stop device and / or a connecting element for fastening a linear stop device is formed on the base 15. A surface normal 15.2 of the contact surface 15.1 lies in an orthogonal plane which is perpendicular to the support plane 11.3 of the base part 11 and intersects the end 11.2 to be aligned on the ridge side and the end 11.1 of the base part 11 to be aligned on the eaves side. In other words, the surface normal 15.2 lies in a plane spanned by the longitudinal axis 11.4 and the longitudinal axis 12.3. The surface normal 15.2 of the contact surface 15.1 points away from the end 11.2 of the base part 11 to be aligned on the ridge side.
In a central region of the contact surface 15.1, a through hole 15.3 with an internal thread is also introduced into the second holder 15 in a direction parallel to the surface normal 15.2. As an element of a screw connection, the bore 15.3 with an internal thread represents a connecting means for the positive and / or non-positive fastening of the linear stop device and / or a connecting element for fastening the linear stop device.

Brackets of the two end devices 10a, 10c attached. In between, the fixed rope 21 is fastened to the second bracket of the third holding device 10b with the rope intermediate holder 23 via the further screws 26b. Furthermore, the two snow guard tubes 25a, 25b are attached to the first holders of the three holding devices 10a, 10b, 10c. The snow guard tubes 25a, 25b run parallel to the fixed rope 21.
At the attachment point of the roller carriage 24, a snap hook 31 is attached with a safety rope 32 attached to it. A person can be secured at the free end of the safety rope 32, not shown in Fig. 6, e.g. about a safety harness.
FIG. 7 shows the person and snow safety system 30 from FIG. 6 in the assembled state on a sloping roof of a building 40 in a top view from the side onto the building side and the roof surface 41 lying above it. The person and snow safety system 30 is included attached to the roof structure in the area of the eaves 43 above the gutter 44 and parallel to it and parallel to the ridge 42. Correspondingly, the fixed rope of the personal safety device runs along the eaves 43 or the gutter 44. A schematically illustrated person 45 is secured to a safety rope 32 on the roller runner 24 of the person and snow safety system 30 and can be moved along the broken arrow in FIG. 7 along the whole Move the eaves 43 or the gutter 44.
However, the exemplary embodiments shown are only to be understood as illustrative examples, which can be modified as desired within the scope of the invention.
For example, 1 also have a different shape, e.g. a U-shape, or consist of other materials. Likewise, the dimensions of the holding device and / or the projection 16 at the free end of the base part 11 can be adapted to the respective applications.
It is also possible to form the holding device 10 in one piece, to omit the strut 13, to replace it with a strut running differently, or to provide an additional strut.
The parts set from Fig. 6 may further include more or fewer parts. For example, an additional rope tensioner can be included. In addition, the holding devices in the set of parts do not necessarily have to be identical or different holding devices can be combined.
It is also possible, for example, to include a securing rail in addition to or instead of the fixed rope 21 in the parts set. This can then e.g. serve as a linear stop device instead of the fixed rope 21.
In the installation on the roof shown in Fig. 7, additional securing elements, e.g. conventional safety hooks or snow guard systems attached above the system 30 in the ridge direction can be used.
With an appropriate design, several people can be secured on the assembled person and snow protection system from FIG. 7, who can work side by side, for example.
In summary, it should be noted that a new and advantageous person and snow protection system has been created, which in particular enables safe work in the area of the eaves. Due to its compactness, the system affects the appearance of roofs only minimally and is easy to retrofit.
