Background of the invention
[0001] The invention relates to a height safety system and more particularly to a safety
line support for anchoring the safety system to a structure of a building or other
construction.
[0002] The invention further relates to a personnel fall-arrest system and a method for
supporting a safety line.
[0003] The field of the invention is defined more specifically in the preambles of the independent
claims.
[0004] When working in heights personnel fall arrest systems need to be used. Such systems
serve to protect workers in situations where they would otherwise be exposed to risk
of serious injury or death by falling. For example, they can be used for protecting
workers on walkways running along the exteriors of structures, high above the ground.
Several solutions have been proposed for providing anchor points on a roof or building
structure for safety lines. Document
DE-102012110659-B4 discloses one example of a safety line support. However, the present solutions have
shown to contain some disadvantages.
Brief description of the invention
[0005] An object of the invention is to provide a novel and improved safety line support,
personnel fall-arrest system, and method for supporting a safety line to a fixed structure
of a construction.
[0006] The safety line support according to the invention is characterized by the characterizing
features of the first independent apparatus claim.
[0007] The personnel fall-arrest system according to the invention is characterized by the
characterizing features of the second independent apparatus claim.
[0008] The method according to the invention is characterized by the characterizing features
of the independent method claim.
[0009] An idea of the disclosed solution is that the safety line support comprises a connecting
part through which safety line is arrangeable so that the connecting part is configured
to surround the safety line, and a bracket part supporting the connecting part and
comprising fastening means for anchoring the safety line support to a structure of
a construction. The support has a single piece configuration, and it is formed of
sheet material. Further, the connecting part comprises at least two ring-shaped elements
having a common axial central line and being located at an axial distance from each
other so that there is an empty space between the two ring-shaped elements. The at
least two ring-shaped elements are configured to be clamped around the safety line
whereby the safety line is mounted immovably relative to the support.
[0010] In other words, the safety line passes through two or more ring-shaped elements and
is visible at the empty spaces between the ring-shaped elements. Thus, the connecting
part is not provided with one single tube, tubular element, or continuous longitudinal
opening, but instead, there are several shorter elements discontinuously arranged
so that they together form a longitudinal passage for the safety line.
[0011] An advantage of the disclosed solution is that the several ring-shaped elements clamp
properly around the safety line and provide firm connection between the support and
the safety line. Since the connecting part comprises several ring-shaped elements,
it withstands well possible deforming forces in fall situations.
[0012] A further advantage of the disclosed solution is that manufacture of the disclosed
safety line support is easy and inexpensive.
[0013] According to an embodiment, width of the empty space of the connecting part of the
safety line support is at least twofold compared to width of the ring-shaped element.
Typically, the width of the empty space is at least threefold.
[0014] According to an embodiment, the safety line is anchored to the connecting part and
is thereby immovably mounted.
[0015] According to an embodiment, the safety line support has a symmetrical structure.
An advantage of this is that the symmetrical safety line support operates properly
in different orientations and positions.
[0016] According to an embodiment, the connecting part has an open position for receiving
the safety line in transverse direction inside the ring shaped elements, and a closed
position wherein the safety line is locked immovably inside the connecting part. The
safety line is easy and quick to push laterally inside the open connecting part, compared
to a solution where the safety line needs to be threaded through the connecting part
for the remaining length of the safety line.
[0017] According to an embodiment, the connecting part is forced to the open position by
means of an internal spring force based on a bend plate material of the support. Thus,
the structure is provided with a self-opening structure, which is normally open and
is configured to be pressed into the closed position by means of separate fastening
screws or corresponding force elements after the safety line is mounted in place.
[0018] According to an embodiment, the connecting part comprises in its open position an
opening, or an open gap, which is dimensioned so that the safety line can be pushed
easily inside the connecting part and it remains inside there temporarily without
easily escaping out of there. Since the safety line remains inside the connecting
part with this temporary hold, mounting of the safety line is facilitated. Final mounting
of the safety line is executed by pressing the structure into the closed position.
[0019] According to an embodiment, each of the mentioned ring-shaped elements of the connecting
part is provided with a lateral mounting opening facing towards the bracket part.
The safety line is mountable inside a free space limited by the ring-shaped element
through the lateral mounting opening when the connecting part is in the open position.
The connecting part further comprises a locking plate protruding laterally adjacent
the mounting opening. The locking plate is configured to be forced against the bracket
part by means of fastening screws for closing the mounting opening, and for setting
the connecting part into the closed position.
[0020] According to an embodiment, the connecting part can be reopened, and the safety line
can be removed from the support. Further, the support can be demounted from the fixed
structure and can be remounted to a new location. Furthermore, also the safety line
may be remounted respectively to a new location.
[0021] According to an embodiment, shape of an inner surface of each ring-shaped element
is circular in a closed position of the connecting part.
[0022] According to an embodiment, the ring shaped element has cylindrical configuration
wherein outer and inner cylinder surfaces are flat surfaces.
[0023] According to an embodiment, transverse dimensions of each ring shaped element are
dimensioned in accordance with transverse dimensions of the safety line so that in
the closed position of the connecting part a press coupling is formed between the
coupling part and the safety line. In other words, the ring-shaped element comprises
an inner diameter in the closed position and the safety line has a substantially circular
cross-section with an outer diameter. The inner diameter of the ring-shaped element
in the closed position may be dimensioned to be slightly smaller compared to an outer
diameter of the safety line. Thus, when the connecting part is forced to its closed
position, then press force is generated between the ring shaped element and the safety
line.
[0024] According to an embodiment, the support comprises three ring-shaped elements, whereby
the support comprises two edge rings, an intermediate ring between them, and two empty
spaces.
[0025] According to an embodiment, the support comprises at least one tooth which is located
between the ring-shaped elements and is facing towards the safety line mountable inside
the ring-shaped elements.
[0026] According to an embodiment, there may be several teeth between the ring-shaped elements.
Number of the teeth may be 2 - 4, for example.
[0027] According to an embodiment, the locking plate comprises at least one first fastening
opening and the bracket comprises at least one second fastening opening whereby at
least one fastening screw is mountable through the openings and is configured to move
the locking plate against the bracket in response to tightening of the fastening screw.
The locking plate has slanted orientation in the opened position of the connecting
part. Further, the tightening of the fastening screw is configured to generate pressing
force to the locking plate and is configured to press the slanted upper surface of
the locking plate downwards and is configured to simultaneously generate lateral force
component for the ring-shaped elements towards the bracket portion thereby generating
tightening lateral forces to the ring-shaped elements of the coupling part.
[0028] According to an embodiment, shape of the at least one first fastening opening of
the locking plate is elongated and is orientated so that its longitudinal axis is
transverse to the axial direction of the connecting part. Then, relative lateral movement
between the fastening screw and the locking plate is possible when the slanted locking
plate is turned from the opened position to the closed position.
[0029] According to an embodiment, the disclosed support can be mounted with conventional
hand tools, such as with battery driven screw drivers. No special tools and skills
are needed in the mounting measures.
[0030] According to an embodiment, the locking plate of the support comprises opposite slanted
axial end surfaces whereby the locking plate tapers towards its free end. An advantage
of the disclosed embodiment is that a glider arranged to glide along the safety line
passes smoothly the support in both travelling directions due to the slanted end surfaces.
[0031] According to an embodiment, the bracket of the support comprises a mounting part
provided with at least one through opening for anchoring screws whereby the support
is mountable to the fixed structure by means of screw fastening. In other words, the
support is mountable in place by means of conventional hand tools. Also, the connection
of the safety wire is based on screw tightening, whereby the entire system is easy
and fast to mount by means of normal tools and the mounting requires no special skills.
[0032] According to an embodiment, the disclosed solution relates to a personnel fall-arrest
system. The system comprises: at least one safety line; two or more safety line supports
for mounting the system to a fixed structure of a construction; at least one safety
harness for at least one user; at least one glider mounted movably to the safety line
and allowed to pass the supports; and at least one lifeline for connecting the glider
to the safety harness. The safety line support is in accordance with the features
and embodiments disclosed in this document.
[0033] According to an embodiment, the safety line extends as a continuous element between
several supports belonging to the system.
[0034] According to an embodiment, the safety line is a metal wire.
[0035] According to an embodiment, the safety line is a stainless steel wire.
[0036] According to an embodiment, diameter of the safety line is 4-14
mm.
[0037] According to an embodiment, the system is without any separate end terminals at distal
ends of the safety line. That is because the supports are fixed to the safety line
and can thereby serve as a kind of end terminals.
[0038] According to an embodiment, the system is easy to reposition. Then the connecting
elements of the supports are opened, and the safety line is removed from the support.
Thereafter, the supports are removed and mounted to a new place.
[0039] According to an embodiment, the supports are mountable to an accessory structure
of a roof of a building, wherein the accessory structure is a service bridge, walkway,
or ladder.
[0040] According to an embodiment, the supports can be alternatively mounted directly to
a roof or wall structure, or cladding. The roof or wall cladding may comprise several
metallic panels fixed on a roof or wall of a building. Also, in this case the supports
are mounted to a fixed structure.
[0041] According to an embodiment, the system is dimensioned to withstand load of several
simultaneous users. In other words, multiple users can be simultaneously attached
to the system.
[0042] According to an embodiment, the disclosed solution relates to a method for supporting
a safety line to a structure of a construction. The method comprises: fastening at
least two safety line supports to the fixed structure at a distance from each other;
and coupling a safety line to connecting parts of the supports. The method further
comprises using supports provided with at least two ring-shaped elements at their
connecting parts and forming a press coupling with the safety line and the support
by pressing the ring shaped elements against the safety line.
[0043] According to an embodiment, strengthening grip between the safety wire and the support
by means of at least one tooth on inner surface side of the connecting part of each
support.
[0044] The above disclosed embodiments may be combined in order to form suitable solutions
having those of the above features that are needed.

Detailed description of some embodiments
[0047] Figure 1 discloses basic components of a personnel fall-arrest system 1. The system
system comprises one or more safety lines 2 which can be mounted to a building or
corresponding construction by means of two or more safety line supports 3. A user
wears a safety harness 4 which is connectable to the safety line 2 by means of a glider
5 and a lifeline 6. The glider can slide along the safety line 2 in accordance with
normal movements of the user on a walkway, for example. If the user falls, then the
user is supported by the system. The glider is designed so that it can pass the safety
line supports. Then the safety line may be long and there may be several supports
at designed distances from each other. One or more user may be connected to the same
system.
[0048] Figure 2 discloses a safety line support 3 comprising a connecting part 7 through
which a safety line 2 is arranged. The support 3 further comprises a bracket part
8 for supporting the connecting part 7 and comprising fastening means 9 for anchoring
the support 3 to a structure of a construction 10. The fastening means may comprise
holes, screws, rivets, or other mechanical fastening elements for providing permanent
or releasable mounting. The connecting part 7 and the bracket part 8 are inseparately
connected to each other i.e., the support 3 has a single piece construction. The support
3 is made of sheet material by means or normal bending, cutting and other sheet metal
work processes and tools. The support 3 may be made of steel material, such as stainless
steel.
[0049] The connecting part 7 comprises two ring-shaped elements 11 having a common axial
central line and being located at an axial distance from each other so that there
is an empty space 12 between the two ring-shaped elements 11. The ring-shaped elements
11 are clamped around the safety line 2 so that the safety line 2 is immovable relative
to the support 3. An advantage of the ring-shaped elements 11 is that when their width
is relatively narrow, they deform relatively easily and can therefore be pressed against
the safety line for producing the effective clamping.
[0050] Figure 3 discloses a connecting part 7 of another support 3. There are three ring-shaped
elements 11a - 11c and two empty spaces 12. Further, at the empty spaces 12 may be
teeth 13a, 13b or other protruding elements, or shapes for further intensifying fastening
strength of the safety line. In Figure 3 there are teeth 13a, 13b in two different
layers or edges on top of each other, but it may be sufficient to have the teeth only
in one layer or edge. In a further embodiment, the teeth may be located on the inner
and/or side surfaces of the ring-shaped elements. In Figure 3 the connecting part
7 is in its closed position CP wherein lateral mounting openings 14 are closed. The
connecting part 7 can be closed by pressing a locking plate 16 against the bracket
part 8 by means of fastening screws 17.
[0051] The locking plate 16 comprises one or more first fastening openings 18 and the bracket
part 8 comprises one or more second fastening openings 19 whereby one or more fastening
screws 17 can be mounted and screwed through the openings 18, 19 for moving the locking
plate 16. As it is shown in Figure 5 the locking plate 16 has slanted orientation
in the opened position OP of the connecting part 7. In Figure 6 it is shown that tightening
of the fastening screw (not shown) generates pressing force to the locking plate 16
and thereby presses the locking plate 16 downwards. Then lateral force component F
(shown in Figure 3) is generated for the ring-shaped elements 11 towards the bracket
portion 8 thereby generating tightening lateral forces to the ring-shaped elements
of the coupling part. This tightening lateral force F is shown in Figure 3.
[0052] Figure 3 further discloses that the locking plate 16 may comprise slanted axial end
surfaces 20. Then the locking plate 16 tapers towards its free end. The slanted surfaces
facilitate the glider to pass the support 3.
[0053] Figure 4 discloses a support 3 wherein a connecting part 7 comprises four ring-shaped
elements 11.
[0054] The bracket part 8 may comprise a mounting part 21 provided with one or more through
openings for anchoring screws 9, 22 whereby the support 3 is mountable to the fixed
structure by means of screw fastening.
[0055] Figure 7 shows a connecting part 7 of a support 3 in an open position OP. A safety
line 2 is inserted inside ring-shaped elements 11 through their mounting openings
14. Diameter of the safety line 2 is slightly greater than size of the mounting openings
14. The safety line 2 can still be pushed inside the ring-shaped elements 11 since
a locking plate 16 may yield and allow the mounting. The safety line 2 stays inside
the coupling part 7 temporarily until the final fastening is done. This way mounting
is quickened and facilitated.
[0056] Figure 8 shown that a protrusion or tooth 13 may move together with a locking plate
16 and may be pushed in a closed position CP against a safety line 2.
